" Vim syntax file
" Language:    FreeBasic
" Maintainer:  Mark Manning <markem@airmail.net>
" Updated:     10/22/2006

" Description:
"
"	Based originally on the work done by Allan Kelly <Allan.Kelly@ed.ac.uk>
"	Updated by Mark Manning <markem@airmail.net>
"	Applied FreeBasic support to the already excellent support
"	for standard basic syntax (like QB).
"
"	First version based on Micro$soft QBASIC circa
"	1989, as documented in 'Learn BASIC Now' by
"	Halvorson&Rygmyr. Microsoft Press 1989.  This syntax file
"	not a complete implementation yet.  Send suggestions to
"	the maintainer.
"
"	Quit when a (custom) syntax file was already loaded (Taken from c.vim)
"
if exists("b:current_syntax")
  finish
endif
"
"	Be sure to turn on the "case ignore" since current versions
"	of freebasic support both upper as well as lowercase
"	letters. - MEM 10/1/2006
"
syn case ignore
"
"	This list of keywords is taken directly from the FreeBasic
"	user's guide as presented by the FreeBasic online site.
