RE: RE: Memory control

Peter,

As Walden points out, "if you get a pointer to a memory location, you
can modify it". I actually use this technique in some of my software. In
one (batch NEP) job, I create a user space in that job's QTEMP, retrieve
the pointer to that user space (using QUSPTRUS) and put the retrieved
pointer into a different 'control' user space in a separate library. Now
a program in a separate job can get to the control user space (because
it's in a normal non-QTEMP library), retrieve the pointer and thus get
at the data in the userspace in the QTEMP of the other job. There's not
even any MI - just plain ol' RPGLE...

I haven't tried putting a pointer to dynamically allocated memory into a
user space, but it would probably work... I'll tinker and see :-) Mind
you, I wouldn't recommend it - it's a real pain to debug :-)
