Qbasic Metacommands are commands that are commented out and start with $.


Syntax:

REM $INCLUDE: 'QB.BI' loads a referance file or library
REM $DYNAMIC
REM $STATIC


  • Metacommands are normally used at the program start and are in effect throughout the program.
  • $INCLUDE can be used at the beginning or at the end of program SUB procedures. Placing the reference elsewhere creates a QB64 compiler error!
  • $STATIC makes all arrays STATIC or unchangeable in size. Use DIM only!
  • $DYNAMIC allows larger arrays that are changeable in size. Use REDIM for changeable sizes!
  • Metacommands should have their own program line since they are commented out.
