Unconditional jumps
Unconditional jumps are jumps which are always executed, because the
condition is always true.
Example:
FN 9: IF +I0 EQU +I0 GOT0 LBLI
Since it is always true that 1 O=lO, the jump will always be executed.
Program example
When Q5 becomes negative, a jump to program 100 will occur.
5 FNO: 05 = +I 0 ___.____...,....................................... Assign value (such as IO) to parameter 05
9
FN 2: 05 = +Q5 - +I2 .......................................
Reduce the value of Q5
10 FN 12: IF +Q5 LT +0 GOT0 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
