EVERY...GOSUB

Define the call of a sub-routine at regular intervals, without interfering with the main program. You must specifying the length of time between every call, measured in TICKS.

Note that the subroutine execution time should be less than the interval time, or the main program timings will be affected. After a subroutine has been entered, the EVERY system is automatically disabled. This means that, in order to call this feature continuously, an EVERY ON command must be inserted into a subroutine before the final RETURN statement.



Define the call of a subroutine 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 subroutine EVERY value/TICKS PER SECONDS seconds.

Note that the subroutine 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. Subroutines 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-subroutines which occurs simultanously to higher-priority-subroutines are not lost. Their task remains or handled again after finishing the higher-prio interrupt.
