Hey folks. This is a bit OT. I've been attempting to build APL-11
for a machine with neither FPP nor FIS, and have hit a wall. I get
multiple "Z" errors from the assembler, which is flagging instructions
whose behaviors differ between PDP-11 models.
Just as a slight side note. Those Z errors are completely fine. The code
is actually tricky, and these instructions are never executed. It's just
the way that the FPP simulation in APL-11 is encoding the arguments to
the simulation. The simulation picks up the MOV instruction after the
call to the simulation in order to find which arguments are used for the
FPP instruction. So ignore those errors.
Has anyone built this from source for something
without FPP/FIS? This
is driving me nuts.
Looking a bit at it, but I need to go away from the computer for a
while. Will be back later.
