8.15.68 CALL MODULE (CM)
8.15.69 CALL MODULE IF LOGIC ACCUMULATOR = 1 (CMT)
1718
Syntax: JPT (JUMP IF FALSE)
Operands: Label (LBL)
Action:
The JPF command is a conditional jump command. If the logic accumulator =
0, the control resumes the program at the label that you have entered. If the
logic accumulator = 1, the control does not jump. The JPF command interrupts
a logic sequence.
Example:
See JPT command.
Syntax: CM (CALL MODULE)
Operands: Label (LBL)
Action:
After a CM command, the control calls the module that begins at the label that
you have entered. Modules are independent subroutines that must be ended
with the command EM. You can call modules as often as you wish from
different places in your program. The CM command interrupts a logic
sequence.
Example:
See CMF command.
Syntax: CMT (CALL MODULE IF TRUE)
Operands: Label (LBL)
Action:
The CMT command is a conditional module call. If the logic accumulator = 1,
the control calls the module that begins at the label you have entered. If the
logic accumulator = 0, the control does not call the module. The CMT
command interrupts a logic sequence.
Example:
See CMF command.
