Because RSI wants you to write more IDL code :-) ! We had a similar problem with
reading large ASCII data files: you read the once ( file1.dat ) and save the data
using SAVE ( file1.dat.sav ). When we re-read the file we check the modification
date of both files and read the newer one. It works fine now but it was written
partly in C to get the modification date of each file also in windows. Anyway,
I read that IDL5.4 will have a full function FSTAT with it.
