In a Display Memory command, the start and ending addresses must be completely specified as 4 digit
hex numbers. To modify a memory location, move the cursor up in the display, type the correction and
press RETURN to enter the change. When you move the cursor to a line to do a screen edit, and press
RETURN, the colon tells the monitor that you are re-entering data.

saved and restored upon each entry or exit from TIM. They may be modified or preloaded as
in the display memory example above. The semicolon tells the monitor you are modifying registers.

The GO command may have an optional address for the target. If none is specified, the PC from the R
command is taken as the target.

LOADING
No defaults are allowed on a LOAD command. The device number and the file name must be completely
specified. Operating system prompts for operator intervention are the same as for BASIC. Memory
addresses are loaded as specified in the file header which is set up by the SAVE command. Machine
language subroutines may be loaded from BASIC but care must be taken not to use BASIC variables as
the variable pointer is set to the last byte loaded
