Usage

How IDMSCALC works

IDMSCALC is implemented as a called subroutine. The utility returns to a user-written program a target page number for storage of a CALC record, based on a page range and CALC key value supplied by the program. The user program, which can be written in any language supporting a call statement, must build a single five-field fullword-aligned argument as outlined in the following table, then call IDMSCALC, passing the argument. IDMSCALC must be link edited with the calling program.
