We have a COBOL program that is using excessive amounts of CPU and have determined that the majority of the time is taking place in a MULTIPLY statement. Thru the use of Compuware's STROBE product we can see that the time is being used by a COBOL module IGZCXMU to perform a Double Precision Multiply. Can anyone tell me what makes COBOL perform a Double Precision Multiply?
The MULTIPLY is coded as such:
MULTIPLY NET-AMT-AT-RISK (WK-INDEX) BY TEMP-2 GIVING TEMP-MORTALITY
NET-AMT-AT-RISK is defined as PIC S9(11)V9(5)
TEMP-2 is defined as PIC S9(9)V9(5) COMP-3
TEMP-MORTALITY is defined as PIC S9(9)V9(2) COMP-3
