'''$INCLUDE''' is a metacommand that is used to insert a source code file into your program which is then executed at the point of the insertion.

{{PageSyntax}}
|
|
:: {[[REM]] | [[REM|']] } $INCLUDE: 'sourcefile'
|
|
|
|
|
|
* Qbasic required that a comment or REM preceded all [[Metacommand]]s at the start of the program.
|
|
* The ''source file'' name MUST have REM or apostrophe comments around the text source file name.
|
|
* $INCLUDE is often used to add functions and subs from an external text QBasic code library.
|
|
* The source file included can contain any BASIC statement except [[GOTO]]
|
|
* QB 4.5 can use [[DECLARE]] SUB in BI files such as [[QB.BI]]. '''QB64''' ignores Qbasic's [[DECLARE]] statements.
|
|
* '''QB64 users can use all statements in their include files. See below.'''
|
|
* The $INCLUDE metacommand should be the only statement on a line since execution progresses ''after'' the code line.

<center>'''How to $INCLUDE a BAS or Text file with a QB64 Program'''</center>
|
|
* '''QB64''' does not require a comment or [[REM]] before any [[Metacommand]]. '''Do NOT comment QB64 specific [[Metacommand]]s!'''
|
|
* The ''source file'' name MUST have REM or apostrophe comments around the text source file name.
|
|
* 1) Assemble your text code into a TEXT file and name it something with a '''.BI''' or '''.BM''' file name extension.
|
|
* 2) $INCLUDE any [[DEFINT]], [[DIM]], [[CONST]], [[SHARED]] arrays or [[DATA]] at the very '''beginning''' of the main program code.
|
|
* 3) $INCLUDE [[SUB]]s or [[FUNCTION]]s at the very bottom of the main program code '''AFTER any SUB procedures.'''
|
|
::: '''Note:''' [[TYPE]] definitions, [[DATA]] and [[DECLARE LIBRARY]] can be placed inside of sub-procedures.
|
|
* 4) '''Compile''' the program with the included text files '''in the QB64 folder!''' Save the text files to use them like '''Library files'''.
|
|
<center>'''Note: Once the program is compiled, the included text files are no longer needed with the program EXE.'''</center>

''Example:'' ''' '$INCLUDE:''' '[[QB.BI]]'

|

''See Library Examples:''
|
|
* [[SelectScreen]] (member $INCLUDE demo)
|
|
* [[FILELIST$ (function)]] (member FILE Search function)
|
|
* [[SAVEIMAGE]] (SUB program that creates bitmaps)
