AFTER...GOSUB

Define the call of a subroutine after a specific time, without interfering with the main program. You must specifying the length of time to wait, measured in TICKS. The ugBASIC branches to the subroutine after value/TICKS PER SECONDS seconds.

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. 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.

Join BASIC 10Liner Contest with ugBASIC!

An interesting competition is held at the beginning of each year: the BASIC 10Liner Contest. It is possible to use ugBASIC to participate in the next "BASIC10Liner" competition, in the following categories:

  • PUR-120 - A game in 10 lines of max 120 characters (w/abbrev.)
  • EXTREME-256 - A game in 10 lines of max 256 characters (w/abbrev.)
  • SCHAU - Any program in 10 lines of max 256 characters (w/abbrev.)
In order to reduce space you can use this abbreviation for this instruction: 

AFTER...GOSUB ↔ Af...Gs
