that corresponds to the module input and output buffers, as shown in the table
below:
You must PUSH the decimal equivalent of the areas of the input and output
buffers that you want to clear. For example to clear the SLC M0 and SLC M1 files
you would PUSH the value 3. The module sets bits 0 and 1 true and clears the SLC
M0 and M1 file areas of the input and output buffers.
Syntax
PUSH [decimal equivalent]
CALL 120
Example
>1 REM EXAMPLE PROGRAM
>10 PUSH 3 : REM CLEAR SLC MO AND M1 FILES
>20 CALL 120
>30 END
CALL 121 – Get SLC
Processor Program ID
Number Purpose
Use CALL 121 to get the ID number of the active SLC processor program. This
routine has no input arguments and one output argument. The output argument is
an integer value between 0 and 65536 that corresponds to the program ID number
of the active program on the SLC processor.
