VARPTR

The VARPTR command (short for "variable pointer") is a pretty advanced statement that lets you get the memory address of a variable. Essentially, it tells you "where" in memory the value of a specific variable is stored.

In some advanced cases, you may want to directly manipulate the contents of memory. This is useful for things like creating custom data structures or optimizing the speed of execution of certain operations.

Directly manipulating memory can lead to program errors that are difficult to detect and correct. If you are not completely sure what you are doing, it is best to avoid using VARPTR.

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: 

VARPTR ↔ Vp
