Re: [Cobolforgcc-devel] MOVE subroutine in UNSTRING

Steven,

You are right. String is OK.

For unstring the receiving area must not be justified but may be
an integer without 'P' in the PIC. So it could be usage anything
- binary, packed, display.

I will have to think about how to structure this.
