IGZCXMU

IGZCXMU is a COBOL library routine that is called when one of the operands of a MULTIPLY verb has 15 or more digits. IGZCXMU is a double-precision multiplication routine that is used with both the RES and NORES compiler options.

Hints

If CPU time is high, determine the maximum size of the operands. If you can define the maximum number of operands to have fewer than 15 digits, you will avoid the use of IGZCXMU.

Refer to the CPU attribution reports to determine which statement called this routine.
