10.6 If-then decisions with Q parameters

Application

The control can make logical if-then decisions by comparing a Q
parameter with another Q parameter or with a numerical value. If
the condition is fulfilled, the control continues the program at the
label that is programmed after the condition.
Further information:
repeats", page 356
If it is not fulfilled, then the control executes the next block.
To call another program as a subprogram, enter a PGM CALL
program call after the block with the label.

Unconditional jumps

An unconditional jump is programmed by entering a conditional
jump whose condition is always true. Example:
FN 9: IF+10 EQU+10 GOTO LBL1
