POKE

The POKE is the write equivalent of the PEEK command, meaning it allows you to modify the contents of a specific memory cell. Essentially, POKE allows you to "write" a numeric value to a particular location in your computer's memory.

In many 8-bit systems, POKE was used to directly configure hardware, such as changing the color of the screen or the sound. By combining POKE with PEEK, you could create custom graphics and sound effects, going beyond the standard ugBASIC capabilities.

POKE gives you very fine-grained control over your computer's memory, and it allows you to create special effects and customizations that would otherwise be impossible. It is a great tool for understanding how a computer works internally.

Improper use of POKE can cause your computer to freeze or corrupt data. Randomly modifying memory can have unpredictable consequences. Valid memory addresses and their meanings vary from system to system.

  • 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:
