" Avenue is the ArcView built-in language. ArcView is
" a desktop GIS by ESRI. Though it is a built-in language
" and a built-in editor is provided, the use of VIM increases
" development speed.
" I use some technologies to automatically load avenue scripts
" into ArcView.
" quit when a syntax file was already loaded
if exists("b:current_syntax")
finish
endif
" Avenue is entirely case-insensitive.
