I don't quite get from your message the dimensions of your
second string variable. Is it of LENGTH 6?

When you need to compare a STRARR(N) against a single string (or more
generally any array against a scalar) use the WHERE function:

indices = WHERE( station_name eq find_this_station )

Read the online help on the WHERE() function...it's extremely useful.

Also useful are UNIQ(), TOTAL(), SORT(), REFORM(), REVERSE()
and SHIFT().
