QJ - Queue Jump
Compatibility: Q drives only
Affects:
Program flow
See also: QG, TI, TR, CR and all Math commands (“R” commands)
Causes program segment execution to jump to the given line number in the queue based on a “condition code”.
Jumps directed to the same line number as the QJ command or past the end of the queue are ignored. If the
condition code is met the jump occurs, if not the program proceeds to the next line. Condition codes are set by
previous commands such as the TI (Test Input) or TR (Test Register) commands. When using math commands
(“R” commands) the condition code is set based on the result of the math operation.
Command Details:
