===== AFTER...CALL ✓ =====

===== SYNTAX =====
     AFTER value[,timer] TICKS CALL identifier

==== PURPOSE ====


Define the call of a procedure after a specific amout of time, without 
interfering with the main program. You must specifying the length of time 
to wait, measured in TICKS. The ugBASIC branches to the 
procedure 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-procedures which occurs simultanously to higher-priority-procedures 
are not lost. Their task remains or handled again after finishing the higher-prio interrupt.



==== EXAMPLE ====
    AFTER 50 TICKS CALL changeBorderColor
    AFTER 50,2 TICKS CALL changeBorderColor
