7 Programming with Q Parameters
7.4 If-Then Decisions with Q Parameters
The TNC can compare a Q parameter with another Q parameter or with a
numerical value for "if-then" decisions.
Jumps
The jump target is specified in the decision block through a label number.
If the programmed condition is fulfilled, the TNC continues the program at
the specified label. If it is not fulfilled, it continues with the next block.
To jump to another program, enter PGM CALL (see page 6-8) after the
block with the target label.
Abbreviations used:

whose condition is always met, e.g.:
FN 9: IF+10 EQU+10 GOTO LBL1
