Try the following macro definition:

    map (tab) (repeat tr (( )))

Every time you hit the TAB key, DME will write as blanks until it reaches
the next cursor position.

I think the newer versions of DME start programs as a background task (just
a guess). That's why you get no output on your current CON: window. But try
this:

    (execute (lc >ram:lcout -L ($filename))
     newwindow newfile ram:lcout
     execute (delete ram:lcout))

[Write all in ONE line, or better, map it to a key]
Now your compiler output should be written in a file named ram:lcout. The
next command will open a new window and will read this file into it. The
third command will delete it from your ram disk.

I do. I use the DME for quite a long time, and yesterday, I bought Lattice.
The reason why very few people care about writing ARexx scrips for this
editor is, I think, because the DME macro language is itself powerful
enough. Not like ARexx, of course, but still, you can really do a lot with
it:-)

You're welcome
