QB64 is meant to be compatible with QB 4.5 or lower versions. PDS (7.1) is not supported. The keywords listed below are currently not supported in QB64. However, older code that uses these keywords won't generate errors, as these are ignored by the compiler.
Keywords not supported in all versions
- ALIAS (supported in DECLARE LIBRARY only)
- ANY
- BYVAL (supported in DECLARE LIBRARY only)
- CALLS
- CDECL
- DATE$ (statement) (reading the current DATE$ is supported)
- DECLARE (non-BASIC statement)
- DEF FN, EXIT DEF, END DEF (must be reworked into actual FUNCTIONs)
- ERDEV, ERDEV$
- FILEATTR
- FRE
- IOCTL, IOCTL$
- OPEN with devices like LPT:, CON:, KBRD:, and other devices is not supported. LPRINT and OPEN COM are supported.
- ON PEN, PEN (statement), PEN (function)
- ON PLAY(n), PLAY(n) ON/OFF/STOP. (PLAY music is supported.)
- ON UEVENT, UEVENT (statement)
- SETMEM
- SIGNAL
- TIME$ (statement) (reading the current TIME$ is supported)
- TRON, TROFF
- WIDTH LPRINT combined statement is not supported.
Keywords not supported in Linux or macOS versions
The commands listed here contain platform-specific calls and may be implemented in the future in Linux and macOS. These commands currently result in stub calls which do nothing.
Desktop and Window calls:
- _ACCEPTFILEDROP, _TOTALDROPPEDFILES, _DROPPEDFILE, _FINISHDROP
- _SCREENPRINT
- _SCREENCLICK
- _SCREENMOVE (available in macOS, not available in Linux)
- _WINDOWHASFOCUS (available in Linux, not available in macOS)
- _WINDOWHANDLE
- _CAPSLOCK, _NUMLOCK, _SCROLLLOCK (statements and functions)
Console:
Modularity: QB64 has no limit on file size so BAS file modules can be combined.
Printing:
Port access:
File locking:
