9.5 If-then decisions with Q
parameters
Application
The TNC 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 TNC continues the program at the label that
is programmed after the condition (for information on labels, see
"Labeling subprograms and program section repeats", page 266). If it
is not fulfilled, the TNC continues with the next block.
To call another program as a subprogram, enter a % program call after
the block with the target label.
Unconditional jumps
An unconditional jump is programmed by entering a conditional jump
whose condition is always true. Example:
D09 P01 +10 P02 +10 P03 1 *
