philbudne a78e9fc1e1 Merge pull request #14 from philbudne/master 
two sets of as7 changes "fixes", and "improvements"
 2016-03-01 11:31:28 -05:00
Phil Budne ff4d793ca5 another round of (hopeful) improvements 
add indirect bit to "sys" definition
set initial ".." (output base) to 4096 (not yet honored)
add "ptr" output format (binary in paper tape reader format: 3 frames of 6 bits)
remove IOT instrictions (system source uses sop.s)
always write labels to "n.out"
add debug output
fix multiply defined error handling (process symbolic labels on both passes)

Warren Toomey 2af2802335 I've moved these working programs into the src/other folder as they are 
not strictly tools.

Warren Toomey a2e8a187b2 tools/a7out: I took out the code to pretend to deal with binary files, 
and I did a perltidy to reformat the code.

Warren Toomey 73c066ae9d I've restructured the opr code and the add code using the SimH logic 
and I fixed up some bugs with the new command interpreter. I'm getting
so close to cat.s working!

Warren Toomey 220f87efed Rewording of the a7out help text. 2016-02-29 17:10:25 +10:00
Warren Toomey 714de5a7e1 I've added a single-step mode to tools/a7out and rationalised the debug output. 
Some small changes to src/cmd/cat.s and wktcat.s to reflect the correct number
of arguments to open. Typos fixes to src/cmd/cat.s.
