The following example shows how to select and run the BASIC program at the
third location from the MVI56-BAS ROM storage area.
Example:
>ROM 3
>RUN
Using the
RROM [program location]
command allows the user to select and run
the BASIC program from ROM area. In this case, it is not necessary to use the
RUN
command.
Example:
>RROM 3
The
ROM
(or RROM) command selects the BASIC program from the ROM area
even if there is a different BASIC program in the RAM memory. For example,
commands such as
LIST
and
RUN
will refer to the program selected from ROM. In
order to select the BASIC program out of RAM memory, the
RAM
command is
used:
>RAM
The PROG1 command loads the port configuration during the power up.
Example:
>PROG1
The MVI56-BAS module allows the user to load the first BASIC program (location
n o 1) in the ROM storage area after the module power up. In order to accomplish
this, the
PROG2
command is used.
Example:
>PROG2
After the
PROG2
command is used, the
PROG0
command can be used in order to
return the module to normal operation.
Example:
>PROG0
To delete the latest BASIC program from the ROM area, the
ERASE
command can
be used:
Example:
>ERASE
In order to check if the current program in RAM will fit in the ROM storage area
CALL 81 can be used.
