Moving a 'S9(7)V99 ' variable to 'S9(7)V99 COMP-3' will not give data exception error i think.

Please check the input variable. It may have non-numeric values.

it has been stated many times and many ways that display numeric data
PIC 9.
will accept anything.

you need to prove that the data contained in the display numeric variable is numeric.

search the cobol forum; there have been many threads.
read the documentation - cobol programmers guide and cobol reference.
button at top of page - IBM Manuals - 2nd from left, will guide you to reference material for your vsn of cobol.

After the signed display-numeric field is packed (internally by the compiler) and then moved (via an MVC) into the receiving packed-field, the compiler issues a ZAP of the packed-field into itself and this is where you can get a S0C7. You won't get a S0C7 on a PACK instruction.
