I wonder if anyone has documentation left on this topic. In the early 80's, I used to be a 3270 terminal operator, and I wrote programs with GIS. I remember that this language was rather mighty but had a steep learning curve. One could write a program (which, of course, was run as a "job"), selecting from several tables, like a relational database. But it was no SQL dialect.Has anyone the "programmer's manual", or a link? I searched the Internet Archive, the IBM website and so on, but no results.best greetings,Andreas
