FNC 04
When FNC 04 (JMP) instruction is driven, program execution jumps
P 40
JMP
unconditionally to the line marked with label P40.
· If this instruction is skipped by another JUMP instruction, this
P 40 Label
instruction is not executed.
1 steps : RET
The subroutine
program whose
No. is equivalent
·
to S is executed.
·
When FNC 02 (CALL) instruction is driven, program execution
jumps to the line marked with label P100 (Operation
·
The subroutine program that starts at P100 is executed, then
program execution returns to the former line No. N300 by FNC
03 (RET) instruction (Operation ).
· The program from label (P) after m02 (m102 for a subtask) to
FNC 03 instruction is regarded as a subroutine program.
Pointers used for CALL instructions should not
be used for JUMP instructions.
•
Program execution jumps to the label specified by
without regard to condition.
