I saw many needs for such batch conversion software.
I wrote for might own use and thought it might be useful to anyone.
So I posted here to share.
Hopes it helps in some way.

Hi

Many thanks for this - I am sure it will be useful to many of our forum users.

Best Regards

I had since receive a number of enquiry on my pico-log convertion code.
It is a short/small program, to helps me to convert to a format that
I can export for other software purpose.

I had updated my website to provide
the *.plw to *.txt code and program for download.

If you are interested in the software,
you can visit my website at,

When I compile your code this is what I get.
