The [$STATIC]($STATIC) [Metacommand](Metacommand) allows the creation of static (unresizable) arrays.
|
|
|
|
## Syntax
|
|
|
|
> {[REM](REM) | ['](apostrophe) } [$STATIC]($STATIC)
|
|
|
|
## Description
|
|
|
|
* QBasic [Metacommand](Metacommand)s 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 [$DYNAMIC]($DYNAMIC).
|
|
* A [REDIM](REDIM) statement has no effect on [$STATIC]($STATIC) arrays except perhaps a [ERROR Codes](ERROR-Codes) at the [REDIM](REDIM) statement.
|
|
* The array's type cannot be changed once [DIM](DIM) and a literal value sets the dimensions and element size.
|
|
* [$STATIC]($STATIC) defined program [arrays](arrays) cannot be [REDIM](REDIM) or use [_PRESERVE](_PRESERVE).
|
|
|
|
## Example(s)
|
|
|
|
When a variable is used, the array can be resized despite $STATIC. The array becomes [$DYNAMIC]($DYNAMIC).
|
|
|
|
```vb
|
|
|
|
'$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](DIM) using a literal numerical size will create a Duplicate definition error.
