WAIT

Pauses execution for a certain period of time. The WAIT statement can be accompanied by a suffix statement, which indicates the unit of measurement of the time to wait. The suffix CYCLES can be used to indicate CPU cycles, TICKS to indicate the number of vertical blanks at 50Hz (PAL) or 60Hz (NTSC), and MS (MILLISECONDS) to indicate a number of milliseconds.

The pause is of the "busy" type, so the entire program is suspended, except for the timer-related mechanisms but including the multithreading mechanism. To avoid this, you can follow the instruction with the PARALLEL keyword, which allows parallel processes to continue executing while waiting for the time.

The PARALLEL keyword can only be used with waits related to CYCLES.

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: 

WAIT ↔ Wt
