536de9ea56 I worked out the bug with the command-line arguments, I was overwriting 017777, oops. I've added more comments to wktcat.s (renamed from simplecat.s). Now we need to find out how the real PDP-7 Unix does command line arguments. Warren Toomey 2016-02-26 21:26:44 +10:00
8f8cc64d10 I've added tad and sza to the a7out simulator, and I also added some code to place command-line arguments into the simulated memory. I'm trying to write my own version of cat so I can compare mine to the real one. Right now there's a bug when simplecat has two arguments. Zero and one arguments are OK! Saving so I have a backup before proceeding. Warren Toomey 2016-02-26 20:56:31 +10:00

c84b2dffdd I've changed the assembler so that it groks the <ab> string literal syntax. I think it's OK, but it probably needs more testing. write_test.s was changed to exercise the string parsing. Warren Toomey 2016-02-26 07:35:36 +10:00
