  • 4ee2619b8c I refactored tools/wktcat.s to lose the repeated code, and I also improved the comments in the code. I'm happy with it, now. Warren Toomey 2016-02-27 11:12:16 +10:00
  • fafeae7470 I've rewritten tools/a7out to have the correct PDP-7 Unix command line memory storage convention, and I've rewritten tools/wktcat.s to deal with this. I've imported some code from the real cat.s and now wktcat.s actually works as per the real cat.s. Warren Toomey 2016-02-27 10:49:43 +10:00

  • d2511c36c0 I'm trying to bring my wktcat.s file into line with the real one. I've refactored tools/a7out to have a dprintf() function to printf only on debugging. I still need to rewrite the command-line arg storage structure. Warren Toomey 2016-02-27 08:05:52 +10:00

  • 6534bd6d43 I renamed simplecat.s to wktcat.s Warren Toomey 2016-02-26 21:28:22 +10:00
  • 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
