Hi,

I looked at the specs for the SETENV command in idl and it says "adds
or changes an environment string in the process environment."
Unfortunately, they only have examples for changing an environment
variable but not how to add to an existing env. variable. I tried
pretty much everything that seems to work in Unix but I didnt get it to
work it in IDL.

so, here is what I am trying to do:
in Unix:
$ setenv FOO "bar"
$ echo $FOO
bar
$ setenv FOO "foo:$FOO"
$ echo $FOO
foo:bar

So, how can you add to an existing env. variable in IDL with the SETENV
command?

thanks

dometz
