the dates in the data file were not compatible with the date format here and
causing errors etc.. once I editied that it started to work.

(another one)

I made that mistake forst time.  right here it deletes nextdate again.

nextdate is being read from the file as "        " which 4dos shortens to
"" so you'll need to use a %format or something when you copy lines to the
temp file,

you'll probably have seen what I mean by now.

Bye.
