OPINION
ON STATE’S MOTION FOR REHEARING
ROBERTS, Judge.On original submission we held that the forgery indictment in this case was fundamentally defective for failing to allege that the appellant passed the check knowing it was forged. We now conclude that this defect is not a fundamental one which may be raised for the first time on appeal.
The pertinent part of our forgery statute, V.T.C.A., Penal Code, Sec. 32.21, reads as follows:
“(a) For purposes of this section:
“(1) ‘Forge’ means:
“(A) to alter, make, complete, execute or authenticate any writing so that it purports:
“(i) to be the act of another who did not authorize that act;
“(ii) to have been executed at a time or place or in a numbered sequence other than was in fact the case;
“(iii) to be a copy of an original when no such original existed;
“(B) to issue, transfer, register the transfer of, pass, publish, or otherwise utter a writing that is forged within the meaning of Paragraph (A) of this subdivision; or
*775“(C) to possess a writing that is forged within the meaning of Paragraph (A) with intent to utter it in a manner specified in Paragraph (B) of this subdivision.
“(2) ‘Writing’ includes:
“(A) printing or any other method of recording information;
“(B) money, coins, tokens, stamps, seals, credit cards, badges, and trademarks; and
“(C) symbols of value, right, privilege, or identification.
“(b) A person commits an offense if he forges a writing with intent to defraud or harm another.”
As we observed in our opinion on original submission, this statute, as written, “would permit finding a person guilty of an offense for the issuing, transferring, registering the transfer of, passing, publishing, or otherwise uttering a forged writing, even though that person had no knowledge that the writing was forged.” Ante, at page 773.
The question is, then, does an indictment drafted under the strict language of this statute sufficiently charge an offense? Only if it does not is the indictment fundamentally defective. Standley v. State, 517 S.W.2d 538 (Tex.Cr.App.1975); American Plant Food Corp. v. State, 508 S.W.2d 598 (Tex.Cr.App.1974).
A reading of the statute reveals that it unequivocally prescribes a single culpable mental state for forgery: This is the intent to defraud or harm, which is required by subsection (b) of Section 32.21. See Teniente v. State, 533 S.W.2d 805 (Tex.Cr.App. 1976). Thus, the requirement of V.T.C.A., Penal Code, Sec. 6.02(a) is satisfied on the face of the statute; subsections (b) and (c) of Section 6.02 simply do not apply.
On original submission we held that the culpable mental state “with knowledge” also “had application” to the offense of forgery. We remain convinced of the soundness of this conclusion, since many of the acts which constitute forgery under Section 32.21 imply a requirement of knowledge on the part of the actor that the instrument was forged. However, this culpable mental state is nowhere mentioned in the statute. The issue, therefore, is whether a forgery indictment which does not allege this implied requirement of knowledge is valid.
As we noted in Baldwin v. State, 538 S.W.2d 109, 111 (Tex.Cr.App.1976):
“Ordinarily an indictment which charges an offense in the terms of the statute is sufficient.”
However, it is also well established that:
“It is not always sufficient to follow the language of the statute. There are cases that require greater particularity, either from the obvious intention of the Legislature or from the application of known principles of law.” 1 Branch’s Ann.P.C., 2d ed., Sec. 514, p. 496.
See also Lucero v. State, 502 S.W.2d 128 (Tex.Cr.App.1973) (case 1); Bouie v. State, 528 S.W.2d 587 (Tex.Cr.App.1975); Page v. State, 532 S.W.2d 341 (Tex.Cr.App.1976).
It seems clear from an examination of our new Penal Code that the Legislature was very much aware of the concept of culpability and the delineation of four carefully defined culpable mental states; in fact, this is one of the major changes in our new Code. See the Practice Commentary to V.T.C.A., Penal Code, Sec. 6.03, and see, V.T.C.A., Penal Code, Sec. 1.07(a)(13); Art. 21.15, V.A.C.C.P., as amended; Art. 37.-09(3), V.A.C.C.P., as amended. This legislative awareness is seen in the forgery statute as well, as we have noted, in the fact that the intent to defraud or harm is made an essential part of the offense. From this we must infer that if the Legislature had desired to make knowledge an essential part of the definition of forgery, it would have done so with clarity and certainty.1
*776Thus, we can conclude, first, that the Legislature did not intend to include knowledge that the instrument was forged an essential element of the offense of forgery, and, second, that legislative intent does not provide a requirement that the State allege such knowledge in an indictment.
The remaining question is whether “known principles of law” require that the State allege that the accused possessed such knowledge. In answering this question we turn first to Section 224.1 of the Model Penal Code, which was relied upon and reproduced in the opinion on original submission. A careful reading of subsection (1) of Section 224.1, as well as subsection (l)(a) and (l)(b) thereunder, makes it clear that one may be guilty of forgery under the Model Code if he has the “purpose to defraud or injure” or if he has “knowledge that he is facilitating a fraud or injury to be perpetrated by anyone.”
It follows that under the Model Code knowledge is not an essential element of forgery if there is a purpose to defraud or injure.
On original submission we also relied upon 18 Pa.Stat.Ann., Section 4101 — the Pennsylvania forgery statute. Section 4101 follows Section 224.1 of the Model Code almost word for word: The only significant difference between the two is that the Pennsylvania statute substitutes the word “intent” for “purpose” in the first subsection of the statute. Therefore, as is the case with the Model Code, the Pennsylvania forgery statute does not make knowledge an essential element of the offense.
The California2 and New York3 forgery statutes — both cited in our original opin*777ion — appear to require an element of knowledge in some instances, but not in others, while the Illinois statute4 — also cited in the original opinion — requires both knowledge and an intent to defraud in all cases.
From this mixed group of statutes we cannot conclude that known principles of law require knowledge as an essential element of the offense where there is alleged an intent to defraud.
Therefore, we hold that an indictment or information for forgery which fails to allege knowledge as an essential element is not fundamentally defective.
However, because knowledge that the instrument is forged is an element which is strongly implied in the statutory definition *778of forgery, we hold that its absence in an indictment is a matter which may be raised by a motion to quash, but may not be raised for the first time after trial has commenced. See and compare Melley v. State, 93 Tex.Cr.R. 522, 248 S.W. 367 (1923); Shipley v. State, 84 Tex.Cr.R. 278, 208 S.W. 342 (1919).
This indictment alleges the offense in the language of the statute, including the requisite intent. There was no motion to quash the i: ndictment. Therefore, the failure to allege knowledge is not before us on appeal.
Next, we turn to the grounds of error raised in appellant’s brief. A summary of the facts is necessary to a discussion of these grounds.
Omitting the formal parts, the indictment alleges that on February 5, 1974, in Potter County, Texas, John Jones did then and there “with intent to defraud and harm, forge, by passing to Jerry Haile,5 a writing as follows:
“AND AFORESAID do further present that pri- or to the commission of the aforesaid offense by the said John Jones, to-wit, on the 6th day of September, A.D., 1968, in the 47th District Court of Potter County, Texas, in cause number 13480 on the docket of said court, the said John Jones under the name of John Arthur Jones, was duly and legally convicted in said last named court of a felony, to-wit: Assault With Intent to Murder Without Malice, upon an indictment then legally pending in said last named court and of which said court had jurisdiction; and said conviction was a final conviction and was a conviction for an offense committed by him, the said John Jones, prior to the commission of the offense hereinbefore THE GRAND JURORS him as set forth in the first paragraph hereof . . charged as
The State’s first witness was Jerry Don Hale, the owner and operator of a liquor store in Potter County. He testified that on February 5, 1974, the appellant entered his store and, in exchange for liquor and cash, gave him the check which is reproduced in the indictment. The check was not endorsed.
D. M. Newton testified that he was a partner in Greater Southwest Enterprises and that in the early part of 19746 he had hired appellant to stack lumber. The appellant worked for one day, and Newton paid the appellant for his work in cash at the end of that day. Newton testified that the appellant agreed to work the next day but *779did not appear. Newton identified the check passed to Jerry Don Hale as one of his company’s checks, but denied that the signature at the bottom of the check was his and also denied that he had authorized anyone to sign his name for him on the company’s checks. He also testified that the company’s checks were ordinarily signed by him and his partner (and brother) C. E. Newton, with his partner signing the first of the two signature lines.
Newton then testified that he was told by the secretary at the Midland National Bank that the check had been passed. At that time he looked in his checkbook and found that three checks, including the one passed by appellant, were missing. He stated that he always kept the checkbook in his pickup and that the appellant had been in the pickup on the day that appellant worked for Newton. He also stated that on one occasion that day the appellant (along with another temporary worker) had been alone in the pickup while Newton was not present inside the pickup.
Finally, Newton testified that he never gave a check, “payroll or otherwise,” to the appellant.
Appellant’s first contention is that the evidence is insufficient to show that C. E. Newton, D. M. Newton’s partner, did not sign the check. Appellant argues that C. E. Newton, as a partner, had authority to bind the partnership and could have signed D. M. Newton’s name to the check. C. E. Newton did not testify.
D. M. Newton’s unequivocal testimony that no one had authority to sign his name to the checks of Greater Southwest Enterprises is sufficient to show that C. E. Newton did not have this authority. See Rice v. State, 484 S.W.2d 589 (Tex.Cr.App.1972); Ware v. State, 475 S.W.2d 282 (Tex.Cr.App. 1972). Cf. Reed v. State, 533 S.W.2d 35 (Tex.Cr.App.1976). Appellant’s contention is overruled.
Appellant next contends that because the instrument was not endorsed, it could not be passed as a forged instrument. The forgery statute, V.T.C.A., Penal Code, Sec. 32.21, is set out on the first page of this opinion and will not be reproduced here.
The testimony of D. M. Newton was sufficient to show, as required by subsection (a)(l)(A)(i) of Section 32.21, that the check was made so that it purported to be his act and that he did not authorize that act. Hale’s testimony was sufficient to show, as required by subsection (a)(1)(B) of Section 32.21, that the check was passed. Hale’s inadvertent failure to require an indorsement is neither significant nor relevant in establishing the offense charged. This contention is overruled.
Appellant next contends that the forgery statute is unconstitutional and in violation of due process because it does not require knowledge that the instrument was forged. Our forgery statute requires that: “A person commits an offense if he forges a writing with intent to defraud or harm another.” Y.T.C.A., Penal Code, Sec. 32.-21(b). This is sufficient to establish mens rea and thereby to satisfy due process in this regard. See V.T.C.A., Penal Code, Sec. 6.02(e), as well as the Practice Commentary to Section 6.02, and see King v. State, 519 S.W.2d 651, 652 (Tex.Cr.App.1975), where it is stated that “the gravamen of forgery offenses is the intent to injure or defraud.” Appellant’s contention is overruled.
Finally, appellant contends that he is entitled to credit for time he served in jail after his arrest but prior to sentencing. The State agrees, citing Art. 42.03, Sec. 2, Vernon’s Ann.C.C.P. (as amended, effective August 27, 1973).
Section 2 of Article 42.03 now provides:
“In all criminal cases the judge of the court in which the defendant was convicted shall give the defendant credit on his sentence for the time that the defendant has spent in jail in said cause, from the time of arrest and confinement until his sentence by the trial court.” (Emphasis added.)
The statute is mandatory. Guerra v. State, 518 S.W.2d 815, 817 (Tex.Cr.App.1975).
Appellant was sentenced on June 20, 1974, after the effective date of the amend*780ment to Section 2 of Article 42.03. The record reflects that the trial judge refused to give the appellant credit for any time he spent in jail prior to sentence. The sentence must be reformed to show that credit is given for time spent in jail after he was arrested. Art. 42.03, Sec. 2, supra; Guerra v. State, supra.
However, the record does not clearly reflect when the appellant was arrested in this cause. This date must be determined in the trial court upon receipt of this Court’s mandate, after which appellant shall be given credit from that date as required by Article 42.03, Section 2. See Guerra v. State, supra, at note 4.
The State’s Motion for Rehearing is granted. As reformed, the judgment is affirmed.
. We realize that the Legislature intended to create some offenses without clearly and certainly prescribed culpable mental states. V.T. C.A., Penal Code, Secs. 6.02(b), 6.02(c). However, because the Legislature did include a culpable mental state within the definition of forgery, it affirmatively omitted forgery from this class of offenses.
. California Penal Code, Section 470 (West), reads as follows:
“Every person who, with intent to defraud, signs the name of another person, or of a fictitious person, knowing that he has no authority so to do, to, or falsely makes, alters, forges, or counterfeits, any charter, letters patent, deed, lease, indenture, writing obligatory, will, testament, codicil, bond, covenant, bank bill or note, post note, check, draft, bill of exchange, contract, promissory note, due bill for the payment of money or property, receipt for money or property, passage ticket, trading stamp, power of attorney, or any certificate of any share, right, or interest in the stock of any corporation or association, or any controller’s warrant for the payment of money at the treasury, county order or warrant, or request for the payment of money, or the delivery of goods or chattels of any kind, or for the delivery of any instrument of writing, or acquittance, release, or receipt for money or goods, or any acquittance, release, or discharge of any debt, account, suit, action, demand, or other thing, real or personal, or any transfer or assurance of money, certificate of shares of stock, goods, chattels, or other property whatever, or any letter of attorney, or other power to receive money, or to receive or transfer certificates of shares of stock or annuities, or to let, lease, dispose of, alien, or convey any goods, chattels, lands, or tenements, or other estate, real or personal, or any acceptance or indorsement of any bill of exchange, promissory note, draft, order, or any assignment of any bond, writing obligatory, promissory note, or other contract for money or other property; or counterfeits or forges the seal or handwriting of another; or utters, publishes, passes, or attempts to pass, as true and genuine, any of the above-named false, altered, forged, or counterfeited matters, as above specified and described, knowing the same to be false, altered, forged, or counterfeited, with intent to prejudice, damage, or defraud any person; or who, with intent to defraud, alters, corrupts, or falsifies any record of any will, codicil, conveyance, or other instrument, the record of which is by law evidence, or any record of any judgment of a court or the return of any officer to any process of any court, is guilty of forgery.”
