I've got a strange issue in which one particular OPM program (OPM RPG, if it makes any difference), when running on one particular box (the one on which it was compiled), is unable to access the INFDS of its display file, and blows up with a "pointer not set" error if it attempts to do so.

At least 2 different revisions of the program have this problem, but only on this particular box. And other programs have no trouble at all accessing the INFDSs of their display files on that box, and neither of the two revisions of the program have the problem on a different box.

Strangest of all, the troublesome program worked fine on the troublesome box back in October.


Any idea what could be going on?
