I'm writting a complete LAP (List Assembly Program) manual.
on the release, the manual will contain:
a LAP assembler, Brief Instruction manual, byte-code decoding manual,
more...
I'm missing pieces of information, information which I couldn't find
elsewhere.
I'll be gratefull if someone could help...
1) what's the purpose of op-code 90 (\132) the instruction byte-diff ?
2) what's the purpose of op-codes, and what arguments do they take on stack?
\220 byte-temp-output-buffer-setup
\221 byte-temp-output-buffer-show
\217 byte-condition-case
thanks
Guy.

It subtracts one number from another.
2) what's the purpose of op-codes, and what arguments do they take on stack?
\220 byte-temp-output-buffer-setup
It does the beginning of with-output-to-temp-buffer,
\221 byte-temp-output-buffer-show
It does the end of with-output-to-temp-buffer,
\217 byte-condition-case
It implements a condition-case. Disassemble a function
that uses condition-case to see how it is used.
