Everything said by Mr Clark is correct. If your problem is more complex than this, I'm afraid you'll have to wait until XXE V2.6 is released (not before February 2004). Super macro-commands, featuring variables (among other things), will be available in this release. Note that today simple macro-commands are fully compatible with tomorrow super macro-commands.
