Tom and Rick's comments about moving the PARM.

There was once a reason, but I've forgotten it.

One of the first things I did when I learnt to write Assembler macros was to 
write my own
initialisation and termination macros, making more use of the save area chain 
conventions than
IBM's equivalents did.

One thing it did was a GETMAIN for the parm length and a move - and there was 
at that time a
solid recommendation to do that.

Thing is - I can't remember why.

The only possible suggestion I can come up with, but feel free to shoot it 
down.  Under the
PCP option of OS/360, the parm field was not protected from write access by the 
program.
Under the MFT option, it was.  Is this a PCP-MFT compatibility issue?
