I remember looking at the source to an old BBS package that would change the PATH environment variable when you shelled to the OS (so it included a message saying "Type EXIT To Return" type thing), and it looked to be quite the hack job.

If you're interested in looking, the source is distributed in an archive called sg20src.zip. Unfortunately it's like 10 megs and you only need a couple files, so that's really overkill. Maybe someone else will have an answer for you though.

Ok,It is something like this:
C:/>read name
(*now reading*)

My question is: how can I set the paramstr(1) "name" into a DOS environment variable with the read(past) string assigned?
Then:
echo %name%

Thank you for your time.

I am not aware of any pascal command for setting
enviroment variables. However this can be achived
by running exec() command. This however could be
limited to current sesion.
Reading of environment vriables is easy. Just check
example in help on GetEnv().

i assume you are using turbo/borland pascal.
open the help and look for GetEnv or SetEnv

But the procedure SetEnv does not exist

you are right, my mistake.
i looked around and found a DosEnv unit you might find useful. didnt
test it though.
