VARIABLES IN COMMON <br /> <br />3.1 Locations of Variables in Common <br /> <br />Appendix C contains a table that shows which subroutines and <br />functions each variable in common occurs in. The table lists <br />where each variable is defined, referenced, or both. <br /> <br />3.2 Definitions of Variables in common <br /> <br />This section gives the definition of each variable that is in <br />common. The definition includes an explanation of subscripts, <br />the units associated with the variable, and the name of the <br />card from which the variable is read, if applicable. <br /> <br />Several clarifications are made below to aid in fully under- <br />standing the definitions: <br /> <br />a. Terminology is defined in section 1 of this manual. <br /> <br />b. occasionally, the name of a variable that is in common <br />is used in another routine, not in common, and therefore has <br />a second definition (ex. CAPMAX in subroutine RESBAL). <br />Definitions would therefore appear in both section 3 and sec- <br />tion 4. <br /> <br />c. In the definition of a flag or switch, a number in pa- <br />rentheses is the value of the variable for the accompanying <br />description (ex. KAM in function FOFX). <br /> <br />d. A description following a subscript means one of two <br />things: <br /> <br />in J = description <br /> <br />the description describes the <br />subscript J (ex. INSEQ) <br /> <br />in J = 3 description <br /> <br />the description describes the <br />variable, when subscript J=3 <br />(ex. IOC) <br /> <br />e. In many cases, a definition given here will not exactly <br />match a definition given in the user's manual. This is usu- <br />ally due to a conversion which occurs immediately after a <br />variable is read into the program. Items read as reach num- <br />bers are usually converted to indices. Items3read as 1,000 <br />acre-ft are often converted to acre-ft or ft Is. <br /> <br />f. Flows given in acre-ft are actually acre-ft/month. <br /> <br />g. If not specified, month 1 means January. <br />h. If not specified, years are stored as four digits. <br /> <br />13 <br />
