[S] extraction from big datafile

Mon, 27 Apr 98 11:34:01 -0500

Dear S'ers:

I have a 127MB file containing about 2,000,000 lines of the following

julian.day latitude longitude TB1 TB2 TB3.......

I need to extract and to store as an S+ object the lines related to specific
list of locations (i.e. pairs lat&lon)

Normally, I do this kind of work in FORTRAN. Is there any good way (comparable
in speed) to perform this kind of extraction in s+?. I work with S+ 3.3,
pent/166/32MGB RAM.

Thank you
