TSS8 and ODTHI

[Rick Adams]

Anyone have a tutorial for me on how to use ODTHI under TSS8?

ODTHI?

Well, I know a little more now, via some searching and experimentation.

If you load a program with LOADER, and use D as the "Option:" value,
your program is loaded, ODTHI is loaded at 7000, and ODTHI is started.

From there you can do:

200/ -- display and allow changing the value at 200 (control-J to go to
the next value)

200G -- start executing at location 200

203B -- set a breakpoint at 203 (there can be only one); when it hits
the breakpoint the value of the accumulator is displayed

B -- remove the breakpoint

C -- continue execution from breakpoint

A -- display and allow changing the value of the accumulator

M -- display and allow changing the value of the MQ

1234W -- display all memory locations containing 1234

Caret and equal sign appear to do something but I don't know what yet.

There are online guides to ODT but TSS8's ODTHI (HI for "loaded into
high memory") appears to be a simplified version.  There doesn't seem to
be any way to single step, for one thing.
