[bionet.molbio.genbank] Sorting order in .idx files

roy@alanine.phri.nyu.edu (Roy Smith) (08/31/90)

	How are the .idx files on GenBank tapes sorted?  More specifically,
if I want to do a keyword binary search through the .idx files, and I use
the standard Unix strcmp(3) routine for comparing my key with the keys from
the file, will I be guaranteed to get the same sorting order as was used to
prepare the files?

The index files on GenBank tape releases are sorted using the standard
Unix sort command.  Therefore I believe that the Unix strcmp command 
should achieve the desired result.
