$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.


Syntax

{REM | ' } $INCLUDE: 'sourcefile'


  • There must always be a REM or ' comment before the $INCLUDE metacommand.
  • The source file MUST have REM or apostrophies around the name.
  • 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. The $INCLUDE of a SUB or a FUNCTION should be after ALL of your program code including SUBs and Functions! Otherwise you will get the QB64 compiler error "Statement cannot be placed between SUB/FUNCTIONs"
  • The $INCLUDE metacommand should be the only statement on a line since execution progresses after the line of the metacommand.
  • $INCLUDE is often used to DECLARE functions and subs used in an external library.


How to $INCLUDE a BAS or Text file with a QB64 Program
  • 1) Assemble your text code into a TEXT file and name it something with a .BI or .BM file name extension. NOT as .TXT!
  • 2) $INCLUDE any DEFINT, DIM, TYPE, SHARED arrays or DATA at the very beginning of the main program code.
  • 3) $INCLUDE SUBs or FUNCTIONs at the very bottom of the main program code AFTER any 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.


Example: '$INCLUDE: 'QB.BI'
