#lang

Preprocessor statement to set the compiler dialect.

Syntax
   #lang "lang"

Parameters
   "lang"
      The dialect to set, enclosed in double quotes, and must be one of 
      "fb", "fblite", "qb", or "deprecated".

Description
   If the -forcelang option was not given on the command line, #lang can be 
   used to set the dialect for the source module in which it appears.  At 
   most two passes will be made on the source module.  On the first pass, 
   if the specified dialect is anything other than the default dialect 
   (chosen with -lang, or "fb" by default), the compiler will reset the 
   parser for another pass and restart compilation at the beginning of the 
   source module.  If this directive is encountered again on the second 
   pass, and the specified dialect does not match the new current dialect, 
   a warning is issued and compilation continues.  If any errors were 
   encountered on the first pass, the compiler will not attempt a second 
   pass."

   #lang may not be used in any compound statement, scope, or subroutine.  
   However, it may be nested in module level preprocessor statements or 
   used in an include file.

   There is currently no restriction on where this directive may be placed 
   in a source module.  In future this may change, therefore best practice 
   would be to use this directive before the first declaration, definition, 
   or executable statement in the source.

   This directive overrides the -lang option if it was given on the command 
   line.  However, if the -forcelang option was given on the command line, 
   this directive will have no effect.  A warning is issued, the directive 
   is ignored, and compilation will continue.  This allows the user to 
   explicitly override #lang directives.

Example
   #lang "fblite"
