The COMMAND intrinsic can cause you grief when moving from V/E to iX.
 
If I remember correctly, we had major problems with programs that used the
COMMAND intrinsic.  I'll have to check the code to be sure, but I think I
ended up writing a procedure named DNAMMOC (command backwards) that was
placed in the CM SL.  It did something with library traps and condition
codes so that it behaved like the MPE V/E COMMAND intrinsic did (ie. it
behaved according to the MPE V/E COMMAND documentation).  When it was
working correctly, the program files were modified so that the references to
the COMMAND intrinsic in the program's externals list were changed to
DNAMMOC.  The CM programs are still in use today at sites around the world
because as of 5.0, the COMMAND intrinsic still does flaky things.
