9.6 If-then decisions with Q parameters

If the condition is fulfilled, the TNC continues the program at the
label that is programmed after the condition.

If it is not fulfilled, the TNC continues with the next block.
To call another program as a subprogram, enter a PGM CALL
program call after the block with the label.
Unconditional jumps

jump whose condition is always true. Example:
FN 9: IF+10 EQU+10 GOTO LBL1
