QBasic 1.1 Commands List: $STATIC Metacommand

Syntax
{REM | '} $STATIC
{REM | '} $DYNAMIC
Description / Parameter(s)
REM | '} REM or a remark character (') must precede metacommands.
$STATIC Specifies that arrays declared in subsequent DIM statements are static arrays (unless they are declared in a non-static SUB or FUNCTION procedure). Array storage is allocated when you start the program, and remains fixed.
$DYNAMIC Specifies that arrays declared in subsequent DIM statements are dynamic arrays. Array storage is allocated dynamically while the program runs.
DIM and REDIM usually provide a better way to specify whether arrays are dynamic or static.
