In addition to vlist, if you have the truss command (AIX has it), you can
see the system calls as they are made. You need a copy of Steven's "Advanced
Programming in the UNIX Environment" handy to decipher it, though (there are
a couple of exceptions on this list; people who actually can read this stuff
on the fly. Frightening.).

I have not had occasion to use the src4uv.com decompiler service.
Probably worth the price when you really need it.
I am thankful for the wonderful www.src4uv.com freebie download,
SRC.UV.HEADER, that allows access to info about the object file from an
I-descriptor subroutine.
Besides VLIST, but similar to it, RAID has the I & X commands that could
be useful when trying to understand EXACTLY what the program is doing:
X Displays the current object code instruction and address.
I Displays and executes the next object code instruction.
