Is there a freeware/shareware/utility to create a program flow diagram
for CL/RPG programs?

Thanks

Generally speaking, no. Data pages and program pages are well defined
from eachother. I would imagine you'd simply get a mrmory fault if you
attempted to change a code page.

And keep the pointer valid? Not sure, don't think so. Then again, I have
heard of someone running PPC machine instructions out of a user space,
so at that point it gets really interesting.

Sure you can mod OS400 data -- but be careful! Changing the global SEPT
is an example. Since most MI opcodes can be accessed from RPG I would
think you might be able to do it in RPG, however, why don't you consider
MI an HLL?
