Syntax

` FB_LANG

`

Description

__FB_LANG__ indicates which language compatibility option was set at the time of compilation of a module. By default __FB_LANG__ will be set to "fb". The language compatibility option can be changed using one (or more) of the following methods:

• -lang command line option
• -forcelang command line option
• #lang directive
• $lang metacommand

Returns a lower case string with one of the following values:

value	description
''fb''	FreeBASIC compatibility (default)
''qb''	QBASIC compatibility
''fblite''	FreeBASIC language compatibility, with a more QBASIC-compatible coding style
''deprecated''	FBC version 0.16 compatibility

__FB_LANG__ is always defined.

Examples

start GeSHi

'' Set option explicit always on

#ifdef __FB_LANG__
  #if __FB_LANG__ <> "fb"
    Option Explicit
  #endif
#else
  '' Older version - before lang fb
  Option Explicit
#endif

end GeSHi
