It's been a while since I've used PL/M, so I may not have the syntax
quite right, but you can implement variable arguments by passing pointers:

call Printf ("format string", @(arg1, arg2, etc));

The biggest thing I missed in PL/M is the pointer op "->".  This op is available
in PL/1 and I always wondered why it was dropped from PL/M.  I wish I had a dime
for every time I wrote:

temp = dir$ptr;
dir$ptr = some$other$ptr;
(do something to dir)
dir$ptr = temp;
