Subject:      SUMMARY:Split variable using regular expression

I received several interesting suggestions to the problem I had posed below,
including a couple that were posted. The solutions were in general of the
following nature.

1. Use perl to identify the files that are to be read in sas via a pipe (and
thus use split to do what I needed)

2. Iteratively search the string to be "split" for various delimiters using
the index function and then substring.

3. Use scan.

1. seemed certainly workable but is ruled out in my case as I had to stick to
SAS. 2 seemed to be a lot of work, but would ensure that I got exactly what I
needed. 3. worked just fine with a bit of modification (some pretreatment of
the string to control for multiple delimiters).

Thanks all.

Hunan.
