LINE INPUT will now use the faster method if passed a file handle that has been opened FOR BINARY. As such, the _BLINEINPUT command has been removed. qb64.bas now takes advantage of this for reading from '$include files, at least in Include Manager 1. Some tweaking of internal/source/main.txt was required to get things into a sane state, so I'm holing off changing the compiler any further so the auto-builder can make sure everything's smoothed over. Note: Everything should still compile as normal; I'm just being overcautious.

The '''$STATIC''' Metacommand allows the creation of STATIC(un-changeable) arrays.

::: REM '''$STATIC'''
|
|
|
|
|
|
* Qbasic [[Metacommand]]s require a REM or apostrophy (') before them and are normally placed at the start of the main module.
|
|
* Static arrays cannot be resized. If a variable is used to size any array, it becomes [[$DYNAMIC]].
|
|
* A [[REDIM]] statement has no effect on [[$STATIC]] arrays except perhaps a [[ERROR Codes|duplicate definition error]] at the [[REDIM]] code.
|
|
* The array's type cannot be changed once [[DIM]] and a literal value sets the dimensions and element size.
|
|
* [[$STATIC]] defined program [[arrays]] cannot be [[REDIM|re-sized]] or use [[_PRESERVE]].
|
|
|
|
|
|
''Example:'' When a variable is used, the array can be resized despite $STATIC. The array becomes [[$DYNAMIC]].

|
{{CodeStart}} '' ''
|
|
'{{Cl|$STATIC}}
|
|
|
|
{{Cl|INPUT}} "Enter array size: ", size
|
|
{{Cl|DIM}} array(size) 'using an actual number instead of the variable will create an error!
|
|
|
|
{{Cl|REDIM}} array(2 * size)
|
|
|
|
{{Cl|PRINT}} {{Cl|UBOUND}}(array) '' ''
|
|
{{CodeEnd}}
|
|
: ''Note:'' [[DIM]] using a literal numerical size will create a Duplicate definition error.
