RE: how do you convert negative packed decimal number ...
JCL is not a programming language it's a script language for executing programs and defining data that programs use. Write a COBOL program to multiply the negative numbers by -1. Then use JCL to execute the program.
RE: how do you convert negative packed decimal number ...
There is no provision in JCL to convert the sign but you can write a sort step to change the sign and this sort step can be run in a JCL. What you would have to do to change the sign is to change the last byte of the packed decimal field from 'XC' to 'XD' where X is a given number varying from 0 to 9.
