- * AREXX Name:Start_TeX.ced Version:1.41 Date:27-Jul-91
- *
- This AREXX script saves and compiles the current CED view. The only
- (optional) argument is the format to be used. A '?' formatname will
- interactively ask for the format to use.
- *
- A command is send to the TeX server to compile the file. Hence a
- return value of 0 does not mean that the file compiled well, but only
- that the command was sent to the server and replied to.
- *
- AUTHOR:
- * J\"org H\"ohle, March 91
- *
- BUGS:
- virtex doesn't like filenames with blanks (and ARexx parses them
- hardly too), so avoid them in file, directory *and* device names.
- *
- Does not like names relative to the local root, like ":foo/bar"
- *
- FILES:
- ENV:TEXFORMAT: default format used
- REXX:namestruc
- *
