EVERY...CALL

Define the call of a procedure at regular intervals, without interfering with the main program. You must specifying the length of time between every call, measured in TICKS. The ugBASIC branches to the procedure EVERY value/TICKS PER SECONDS seconds.

Note that the procedure execution time should be less than the interval time, or the main program timings will be affected.

There are 8 delay timers from 0 to 7 which can be specified with timer. If omitted timer defaults to 0. In the case of parallel task has 0 the highest and 8 the lowest priority.

With EVERY OFF and EVERY ON you can disable or enable the timed calls. Procedures run as long as the main loop / program runs, even the main programm is paused. It is important to know or realise that low-priority-procedures which occurs simultanously to higher-priority-procedures are not lost. Their task remains or handled again after finishing the higher-prio interrupt.
