It was defined in lowercase and has now been made upper case for consistency.
The code which performs the match also has been change to do a case
insensitive compare.
These changes facilitate more robust parameter type checking and helps
to identify unexpected coding errors.
Most simulators can now also be compiled with a C++ compiler without
warnings.
Additionally, these changes have also been configured to facilitate easier
backporting of simulator and device simulation modules to run under the
simh v3.9+ SCP framework.
This reverts commit 5551a0dd9c.
The original idea was that the state being put into simh registers would be required to have all useful information available when remote console executed commands. These steps were taken from the code that sim_instr() executed as it was exiting. After this change was made it was realized that once a remote console command executed it might change state that directly affected instruction execution. To solve this, the logic that executes before the instructions in sim_instr() would then need to be executed whenever the event dispatch processing completed. This approach is messy, burdensome and potentially a lot of overhead for every event dispatch even though almost none of the event dispatches would be for remote console command execution. A completely different approach was suggested by J. David Bryan. That alternative approach would be to have remote console commands execute outside of the sim_instr() routine. Thus allowing the existing prelude and postlude code in sim_instr() to be performed naturally and let the remote console activities run in the same context as all other simh commands. Recent changes to scp and sim_console implement this alternative approach and thus these original changes are completely irrelevant and are thus being removed.
The goals here being to simplify calling code while getting consistent output delivered everywhere it may be useful.
Modified most places which explicitly used sim_log or merely called printf to now avoid doing that and merely call sim_printf().
Finishing the last DECtape device which was missed when this functionality was added to pdp11_dt, pdp18b_dt and pdp8_dt
in commits: 2934112a70 and c9e8121c16
Cleaned up the pdp11, pdp18b and other pdp8 implementations to make backporting cleaner.
Made sure that buffer flushing happens correctly when simulation returns to the sim> prompt.
