Numeric expressions

A numeric expression has the following format:

result=operand operator operand

• Result: Any user variable or job submission variable.
• Operand: Any variable, or a numeric constant.
• Operator: One of the following Variable operators:
  • %%PLUS represents the "+" operator
  • %%MINUS represents the "-" operator

Syntax rules

The following syntax rules apply to a numeric expression:

• Only one operator can be used in each expression.
• There should be no spaces immediately before or after the "=".
• There must be spaces before and after the operator.

  NOTE: When specifying Variable functions that return dates, such as %%$CALCDATE or %%$DATE, there should be no spaces between the + (plus) or - (minus) sign and the number of days to add or subtract. In this case, the + and - signs are not considered numeric expression operators and are not related to the rules specified here.

• In the following example, %%YESTERDAY resolves to 0 on July 1:

  %%YESTERDAY=%%DAY %%MINUS 1

• In the following example, %%PARM1 resolves to 46 on February 5th:

  %%X=%%RJULDAY %%MINUS %%DAY
  %%PARM1=%%X %%PLUS 15
