Detect when Advantage Module solver is running?

I'm trying to figure out if it's possible for a program to detect that it's being run by SOLVE, and I don't see any mention of this in the Advantage manual.

I can give you a firm "I don't know", BUT, if it did, it almost certainly would have been documented, so likely not.

That said, there was talk back in the day, that some modules used some FLAGS for their own reasons in their own code, but current status was saved on entry and restored on exit, under the assumption that doing so would not affect user code expectations. But I don't recall the details, or even if it was HP modules that were being discussed.

Look in the PPC ROM manual under the programs related to flags, it's a likely place this would have been discussed.
