+" Language: Euphoria 3.1.1 - supports DOS - (http://www.RapidEuphoria.com)
+" Maintainer: Shian Lee
+" Last Change: 2014 Feb 23 (for Vim 7.4)
+" Remark: Using 'euphoria3.vim' if "$EUDIR\BIN\EX.EXE" or "$EUDIR/bin/exu"

+" Filetype: *.e, *.eu, *.ew, *.ex, *.exu, *.exw (also in UPPER case).
+" note: *.e|*.E are used by Eiffel; for solution see :help filetype.

+" Quit if a (custom) syntax file was already loaded (compatible with Vim 5.8):
+if version < 600
+ syntax clear
+elseif exists("b:current_syntax")
+ finish
+endif
+
+" Should suffice for very long expressions:
+syn sync lines=40

+" Euphoria is a case-sensitive language (with only 4 builtin types):
