Latest revision as of 18:13, 6 December 2024

Starting with QB64-PE v4.0.0 the compiler provides a huge set of preset CONST values. The list of constants shown below is available for use in every compiled program. Note that the names of all these preset constants have to be preceeded with an underscore, just like all the other QB64(PE) specific keywords.

Libray makers can use the the also new _QB64PE_ precompiler flag in their include files to find out if these new preset constants are available for use or not.

Note
  • You cannot copy and paste the following list into the IDE. Due to the use of underscore names the IDE would immediately throw "Invalid name" errors. Those names can only be defined internally.
  • We just made the list in this familiar program like format, so you can easily see how the constants are defined and which OS/BITS relevant distinctions are made.
