b. (Area Code). The area code refers to the production area which
 the budget is to represent. The number of a production area may
 be obtained either from the map, or from the list of county
 numbers and production areas, included in Appendix II. If this
 budget is to represent production area two, then a '2' would be
 entered as part b. of the budget identification code.

 c. (County Code). The county code is obtained in much the same
 manner as the area code, and facilitates greater detail in the
 specification of the geographic area to which the budget will
 apply. The list of county numbers to be used in the county
 code is included in Appendix II. Should the user wish a budget
 to represent an entire production area, without any county dis-
 tinctions within that area (as in this example), the user should
 enter '00' as the county code (part c.) of the budget identifi-
 cation number.

 d. (Irrigation Level). The relevant codes and their associated
 ranges of irrigation water are shown in Appendix II, Part d.
 For a dryland budget such as the corn grain example, an irriga-
 tion level code of 'O' is entered.

 e. (Land Class Code). The ten possible land class codes are shown
 in Appendix II, Part e. These codes separate land into various
 types and drainages representation of Florida. For the sample
 budget the appropriate land class entry is '4'.

 f. (Grazing Code). The specification of a grazing code, Appendix II,
 Part f, is appropriate only when the enterprise code entered as
 part a. of the budget identification number is '136'. The grazing
 code then identifies the type of grazing produced. In no grazing
 is produced as the principle product of the enterprise a '0'
 should be entered for the grazing code.

g. (Machinery Complement). A total of fifteen machinery comple-
 ments are available for use. The number of the selected comple-
 ment should be entered, although the most common will be '01',
 the default machinery complement shown in Appendix V.

h. (Irrigation System). The possible irrigation systems are shown
 in Appendix II, Part h, although for the dryland corn grain
 example the appropriate entry is '0', implying no irrigation.

i. (Price Vector). A total of nine price vectors, or price sets,
 are available for use. Thusfar, however, only one such vector
 has been developed and the appropriate entry for price vector
 is '1'.

j. (Individual Number). For some budgets all of the above numbers
 will be identical. For instance, budgets might only differ by
 the interest rate charged, or by the timing of certain operations.
 In such cases the two digit individual number, starting with
