Since you use the ASSEMBLE keyword I take it your looking at a SPL program
and wanting to modify it. The EDIT PB instruction is quite indepth and too
much to cover through e-mail. The instruction points to two data addresses,
the source and destination and an address to a program, which could be
located in PB or DB, where several 8bit instructions are written to be
executed by the call to EDIT. The manual I have is "Machine Instruction Set
Reference Manual" Manual Part # 30000-90022 Index No. 3GENL.320.30000-90022,
3rd Edition 02/80. Let me know if you have the manual, if not maybe I can
fax you the pages you need. Which is pretty much all of section 4

Can anyone give me information on the EDIT PB instruction?  I'm assuming it
existed on the Series II and I know that it's octal 20470 and that you
push onto the stack the address of a "program", a destination pointer, a
data pointer (all word addresses, I believe) and a 0 and then
  ASSEMBLE(CON %20470)

Any guidance would be greatly appreciated.  Neither the SPL manual nor the
software pocket guide (which claims to list the series II instruction set)
admit to such a thing existing.  I'm needing to modify the "program".

Thanks,
Ted
