- push new action commands ahead of any previously unprocessed pending
action commands.
- Add ACTION and DO debug to CPU (SCP) command processing support
- Insert %n command arguments before storing command line for potential
deferred processing of action parameters to some commands (IF, BREAK,
EXPECT, etc.)
- Conversion to postfix ends up with operator ordering in different from the
initial assumption resulting all relative compares being wrong.
- Parsing of Hex, Binary and Octal numeric tokens need to properly terminate
- Environment variable names can start with the _ character
If the CPU is a model 1, then the value of idxb is irrelevant. For
tidiness, it should always be 0, but on a model 1, idxe (index
enable) is always 0, so idxb is not looked at. Thus,
- on a model 1, idxb is set to 0, which is harmless and probably a good
thing to do.
- on a model 2, idxe is set to 1, and idxb is set to 0, which is the correct
behavior.
Note that case 0 doesn't need to check for model 2, because clearing
idxe and idxb yields the correct settings on a model 1: indexing is off.
- Assure that Internal variables are referencable during expression evaluation
- Add DEVNAME.REGNAME format for referencing non unique registers in
expression evaluation.
- Extend global register search to also search known internal device list
registers
- Allow expression variable names to have _ as a character within in the name
The SDS tape unit can't do write reverse (no magtape tape can, afaik).
So instead of testing for a particular write subop, the code just tests
that the write was done in BCD mode.
This is closer to how the hardware works.
The goal of the logic in _tmxr_activate_delay() is to properly schedule the next
poll activity considering input and/or output data rates that may be in effect.
We need to make sure that one more poll is scheduled after output data has
been sent since simulation logic may have deferred queuing output data for
other reasons and handles its reactivation in the same context that it polls for
output.
Also, change sim_dir_scan on all platforms to NOT return the contents
of a directory unless the filespec string asks for it. This avoids the
potential catastrophe of a DEL command specifying a directory and
having its contents deleted.
Meanwhile, the DIR command now will list the contents of a directory
if the directory is specified with (or without) a wild card pattern.
