subject: Nodelist...

Hello Gerald!
Quoting Gerald's message:
 GM> Yup!  I get an new ASCII Nodelist from my boss and I want to move it to
 GM> my \NODELIST directory and at the same time, I want to move the old
 GM> nodelist to my \OLDNODE directory (so there is only one nodelist for 
hat
 GM> particular Net in the directory at one time).
Is that nodelist produced on the same day (ie: Monday ... Friday) and is the 
extension constant (ie: A##, Z##, etc. the ## representing the last two 
digits of the Julian day number)?
 GM> I had tried using the extension of the file, the date of the file,
 GM> the size of the file and tried a comparison test of the two, with
 GM> less than spectacular results.  I think if I can use the date of the
 GM> two files to do the comparison testing, this may yield more promising
 GM> results.
 GM> Have you got a solution?
I might have a solution that I have been using for years to process the newly 
arrived FidoNet nodediff and delete the nodediff that is older than 21 days.
Note: This file is based on the Friday - to change the day of the week, 
modify the value of the D_DAY variable according to the information.
