Re: RE: W-Code (was modify program object)

I suppose with CHGSYSLIBL before CRTCMOD/CRTRPGMOD etc, one could: (1)
preempt QWX* programs, extract & disassemble the incoming W-code from the
parameter list, study and interpolate and insert additional W-code into the
stream; and, (2) preempt QBN* programs, extract & disassemble the incoming
NMI from the parameter list, study and interpolate and insert additional
NMI instructions into the stream.  Surely, no harm in that, right?  After
all, the code eventually goes through the trusted RISC translator, so,
altering the higher level W-code or NMI isn't a security threat.
