segment vector with missing data [message #63366]

Hi all -

This should be an easy problem, but I'm having a hard time figuring it
out without using a bunch of loops. I've got a vector with N-elements
(typically N~1000, but could be any number), with some NaNs
interspersed. Typically, there will be a block of NaNs together, but
a single NaN by itself is also possible. I want to extract the short
segments of good data, and their corresponding indices from the
original vector.

I can do something like this, but there has to be a better way

good=FINITE(data)
i=0L
WHILE i LT N_ELEMENTS(data) DO BEGIN
IF i EQ 0 THEN i++ ELSE BEGIN
