Hello all,
I've question which I'm not sure of, when a program is dynamically linked, are the values retained in working storage if that program is called multiple time from the same source? Please help.

Yes they are.

In general, yes. However, it is possible to use INITIAL in the IDENTIFICATION DIVISION of the subprogram or CANCEL in the PROCEDURE DIVISION of the calling program to reset a subprogram to its initial state in which case any changes to variables would NOT be retained.

Also note the values in the LOCAL-STORAGE SECTION are reset on each entry into a program, if you use LOCAL-STORAGE (this is with or without IS INITIAL).
