Hi guys,

This is veering offtopic, but I'd just like to add my two cents.
IDL, like C, has many constructs that may add placed on a line to
condense the actual length of the program. However, just like C, the
readablity and understanding factors tend to drop. I intend to use the
a=(b=(c=1)) example. I always wondered how to initialize multiple variables
on the same IDL line.

Thanks,

Bill B.
