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
