Until I got a received the copy of the message I just sent out, I didn't
realize how the formatting could get messed up. Since that could make
the nature of my problem somewhat unclear, let me repost it, with some
slight reformatting. My apologies for any possible confusion. --Glenn

Hoping someone can help me with a problem involving dividing up a
variable. My data consists of patent numbers (wku) and inventors (nmi)
and looks like this:
Record 1
NMI: Schmitt, Ty; Gandre, Jerry WKU: 5586003
Record 2
NMI: Sato, N. Albert; Baker, David C.; Waldron, Christie J. WKU:
5586324
Record 3
NMI: Swamy, N. Deepak WKU: 5587885
I would like it to look like this:
nmi wku
Schmitt, Ty 5586003
Gandre, Jerry 5586003
Sato, N. Albert 5586324
Baker, David C. 5586324
Waldron, Christie J. 5586324
Swamy, N. Deepak 5587885
That is, I want to create a record containing each inventor and his or
her associated patent number. If Ty Schmitt had five patents, he should
show up in five records. The number of inventors per patent varies from
one to many.
I've looked for egen functions (and their extensions) and done some
experimenting, but am floundering. Any help would be very appreciated!
