$STATIC - QB64Official/qb64 GitHub Wiki

The $STATIC Metacommand allows the creation of static (unresizable) arrays.

Syntax

{REM | ' } $STATIC

Description

  • QBasic Metacommands require a REM or apostrophy (') before them and are normally placed at the start of the main module.
  • Static arrays cannot be resized. If a variable is used to size any array, it becomes $DYNAMIC.
  • A REDIM statement has no effect on $STATIC arrays except perhaps a ERROR Codes at the REDIM statement.
  • The array's type cannot be changed once DIM and a literal value sets the dimensions and element size.
  • $STATIC defined program arrays cannot be REDIM or use _PRESERVE.

Example(s)

When a variable is used, the array can be resized despite $STATIC. The array becomes $DYNAMIC.


'$STATIC

INPUT "Enter array size: ", size
DIM array(size)   'using an actual number instead of the variable will create an error!

REDIM array(2 * size)

PRINT UBOUND(array)

Note: DIM using a literal numerical size will create a Duplicate definition error.
