" 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.
" For version 5.x: Clear all syntax items
" For version 6.x: Quit when a syntax file was already loaded
if version < 600
syntax clear
elseif exists("b:current_syntax")
finish

syn keyword aveStatement if then elseif else end break exit return

" Integer number

" Operator
syn keyword aveOperator or and max min xor mod by
" 'not' is a kind of a problem: Its an Operator as well as a method
" 'not' is only marked as an Operator if not applied as method
