The question presented by this application to assume original jurisdiction and petition for writ of mandamus is whether the State Board of Equalization [Board] is required, pursuant to the Okl.Const. Art. 10, § 23,1 to certify the total amount of revenue which accrued to the General Revenue Fund and each special fund during the last preceding fiscal year.
The Board by a majority vote 2 refused to certify each special fund for fiscal year 1982. Two members of the Oklahoma State Senate, Finis W. Smith and John W. Young, petitioners, seek to compel them to do so.
It is undisputed by the parties that this is a matter of publici juris and that this Court *1266has jurisdiction.3 What is disputed is the necessity for the Board to certify and estimate earmarked or dedicated funds which the Legislature has appropriated on a continuing basis. The respondents contend that since 1941, when Art. 10, § 23 was adopted, the Board has certified only those funds appropriated by the Legislature on an annual basis. The Board’s decision not to certify all special funds purportedly was based on its determination that the Legislature had better facilities to determine the possible receipts of continuing appropriations. The respondents also argue that: 696 funds are appropriated on a continuing basis; the task of estimating these funds is too burdensome; and certification of funds under Art. 10, § 23, which are earmarked, would provide information of no value because these funds are already appropriated. The respondents also assert that because Art. 10, § 23(5)4 provides that in the event the Board fails to file an estimate, the Legislature shall do so, it is not a mandatory duty of the Board.
The petitioners and the amicus curiae allege that Art. 10, § 23 requires that the Board “shall” estimate revenues accruing to the General Revenue Fund and each special fund; and that both classifications are subject to the constitutional limitations to prevent non-appropriated expenditures and to prevent deficit spending. The assertion is also made that the estimation of all revenues is not an impossible task nor is it unduly complicated or burdensome. We agree.
The constitutional requirement that the Board shall certify the total amount of revenue which accrued to the General Revenue Fund and each special fund during the last preceding fiscal year is clear, mandatory, and unambiguous. “Shall” is commonly understood to be a word of command which must be given a compulsory meaning.5 “Accruing” connotes periodic accumulation, growth increase, or augmentation.6 Appropriation, as contrasted to accruing, is the designation or authorization of the expenditure of public moneys and stipulation of the amount, manner and purpose for a distinct use or for the payment of a particular demand.7
The crux of this question is what is a special fund within the contemplation of Art. 10, § 23? This Court in Draper v. State Bd. of Equalization, 414 P.2d 276, 279 (Okl.1966) defined special funds as including only those funds which are supported by direct taxes, fees, or other revenue.8 In *1267order to qualify as a special fund the account must directly receive revenue in the form of taxes, fees, charges, costs, grants, or other revenue.
We are not persuaded by the argument that continuing funds are not subject to certification. The court adopted the premise in State ex rel. Hawkins v. Oklahoma Tax Commission, 462 P.2d 536 (Okl.1969) that the earmarked continuing special gasoline excise tax was subject to the provisions of Art. 10, § 23.
For example, the Technical and Scientific Education Special Fund, a separate and continuing fund, created for the general purpose of technical and scientific education in vocational, technical and scientific schools or junior colleges receives 92% of the documentary stamp tax.9 It is a special fund with the Draper definition of a fund which directly receives moneys in the form of fees, charges, costs, grants, or other revenue, and it must be certified by the Board for appropriation by the Legislature. The Court is unable to determine precisely how many special funds require estimation by the Board from the record. However, we hold that all funds which receive funds from taxes, charges, costs, grants, or other revenue are within the purview of Art. 10, § 23.
Article 10, § 23 was adopted by the people in 1941 to provide for budget balancing in this state. There is no room for construction or provision for further inquiry when the Constitution plainly speaks. A constitutional amendment should be construed in consideration of its purpose and be given a practical interpretation to carry out the plainly manifested purpose of the people who adopted it.10 The fiscal responsibility shown by Oklahoma has become an enviable example for the nation. This policy of fiscal restraint and control can only be applauded in a time of monetary crises. We do not find this constitutional requirement to be unduly burdensome nor to be a vain endeavor. The citizens of this state, as well as the Legislature, have a vested constitutional right to know how much money is available for appropriations to the General Revenue Fund and special funds which are supported by direct taxes, fees, or other revenue.
Because of the long standing administrative interpretation by the Board of Art. 10, § 23, we find that it would not be wise to disrupt governmental functions in process during fiscal year 1981.11 We, therefore, order that when the Board next meets to estimate and certify the total amount of revenue which accrued to the General Revenue Fund and each special fund during the last preceding fiscal year, it shall certify each special fund which directly receives funds in the form of taxes, fees, charges, grants, or other revenue.

“Our attention is invited to the Emergency Appropriation Fund which was created by the Legislature in 1947. 62 O.S.1961, Sec. 9.1-9.8. It is argued that the Emergency Appropriation Fund may be treated as a ‘special fund’ under Section 23, Constitution, supra. This argument is untenable. Special funds, in the contemplation of Section 23, include only those funds that are supported by direct taxes, fees or other revenue. The Emergency Appropriation Fund consists of ‘all moneys transferred, or authorized to be transferred by the Legislature from any surplus cash arising incidentally from receipts in excess of appropriations to the credit of other funds in the State Treasury.’ 62 O.S. 1961, Sec. 9.2. In other words, accruals in the Emergency Appropriation Fund are not revenue, but such fund is simply a convenient account in which to transfer surplus funds from the General and Special Funds not needed to pay current year appropriations.... ”
