7 Programming with Q Parameters
7.4 If–Then Operations with Q Parameters
Unconditional jumps
Unconditional jumps are jumps which are always executed because the
condition is always true.
Example:
FN 9: IF +10 EQU +10 GOTO LBL1
Since it is always true that 10=10, the jump will always be executed.
Program example
When Q5 becomes negative, a jump to program 100 will occur.
5 FN0: Q5 = +10 ................................................... Assign value (such as 10) to parameter Q5
9 FN 2: Q5 = +Q5–+12 ......................................... Reduce the value of Q5
10 FN 12: IF +Q5 LT +0 GOTO LBL 5 ..................... If +Q5 is less than 0, jump to label 5
15 LBL 5 .................................................................. Label 5
16 PGM CALL 100 ................................................... Jump to program 100
