Note: V4 is suppose to have that fixed(nestingmacros)

There's a V4?  I'm stuck with Tormach's current release, need a workaround.

Then try the semaphore approach it does seem to work.  Do a search on this forum for semaphore Ray gives and example of how he did it.

If you don't actually want or need the parallel behaviour of the multiple macros, it seems a bit overkill to start messing with home rolled semaphores just to get a "sub call". Why not just put your library routines in... erm... a library i.e. a DLL?

Cheers
