$INCLUDE: Difference between revisions

Revision as of 10:30, 29 January 2023

$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.

{REM | ' } $INCLUDE: 'sourceFile'

QBasic metacommands must be commented with REM or an apostrophe.
The sourceFile name must be enclosed in apostrophes and can include a path.
$INCLUDE is often used to add functions and subs from an external text QBasic code library.
The $INCLUDE metacommand should be the only statement on a line.

Assemble the code to be reused into a file.
Common extensions are .BI (for declarations, usually included in the beginning of a program) or .BM (with SUBs and FUNCTIONs, usually included at the end of a program).
- Any extension can be used, as long as the file contains code in plain text (binary files are not accepted).
$INCLUDE any DIM, CONST, SHARED arrays or DATA at the beginning of the main program code.
$INCLUDE SUBs or FUNCTIONs at the bottom of the main program code after any SUB procedures.
- Note: TYPE definitions, DATA and DECLARE LIBRARY can be placed inside of sub-procedures.
Compile the program.
Note: Once the program is compiled, the included text files are no longer needed with the program EXE.
