Nuts, its been about 6 years since I used gentran:basic but I will take a stab at it. It is a strange duck compared to the other gentrans for many reasons. One a section is gone- header, line, footer - there is no way to reference it again. You can't be in the PO1 and access something in the BEG segment, for instance. The way you pass data across sections is by the use of constants - a limited number at that. Another thing is that the first thing you write in a field wins rather than the last thing you write as in the windows visual mapper products.
I thought there was a way to arrange rules on a field to execute in a particular order. Reference the documentation on Sterling's site if you can. Then perhaps you could store the GS ID as Leah suggested in a constant at the header always and then use it later if you need it. I hope that will, with the help of the documentation, point you in the right direction. Gentran: Basic was the first mapper I ever used and I remember making many "WHOOPEE" exclamations the first time I got to use the Gentran Server mapper. That one operates under the same principles most of us take for granted now. I wish for your sake I had not been so successful in erasing the memories of that old dinosaur. I vaguely remember JCL too. If I sat down at the old screen I feel certain my hands would remember more than my brain does.
