Re: Suggestions

There are LOTS of problems with this technique.  Suppose your key's are 
1,3,4,7,8,9 (with some having been deleted).  Now you RGZPFM and get rid 
of the deleted records.  Using your technique, the current high key would 
be 6.  Nice try with counting the number of deleted records though.

Re: Suggestions






This program returns the number of records in the file.  Just add 1 and 
use as the key, unless you decide to begin teh keys with zero.
