" Description:
"
" Based originally on the work done by Allan Kelly <Allan.Kelly@ed.ac.uk>
" Updated by Mark Manning <markem@sim1.us>
" 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.
"
" TODO: split this into separate dialect-based files, possibly with a common base
"
" Quit when a (custom) syntax file was already loaded (Taken from c.vim)
"

" Do the Basic variables names first. This is because it
" is the most inclusive of the tests. Later on we change
" this so the identifiers are split up into the various
" types of identifiers like functions, basic commands and
" such. MEM 9/9/2006
