" Vim syntax file
" Language:	ibasic
" Maintainer:	Mark Manning <markem@airmail.net>
" Originator:	Allan Kelly <Allan.Kelly@ed.ac.uk>
" Created:	10/1/2006
" Updated:	10/21/2006
" Description:  A vim file to handle the IBasic file format.
" Notes:
"	Updated by Mark Manning <markem@airmail.net>
"	Applied IBasic 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.
"
"	This version is based upon the commands found in IBasic (www.pyxia.com).
"	MEM 10/6/2006
"
"	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 basic
"	support both upper as well as lowercase letters.

"	Do the basic variables names first.  This is because it

"	this so the identifiers are split up into the various
"	types of identifiers like functions, basic commands and
