When IDL had their 5.0 seminars a few months back, I mentioned
this problem to RSI, and suggested that XMANAGER print out the
line number of the error statement. We can only hope it's
included in 5.1! I also could not get CATCH = 0 to "do the
right thing", especially when using multiple top level bases.
