If you're using cygwin, I believe it works just the same as on a
Unix/Linux system:

    VAR=value program

for setting VAR just for a single run; or:

    export VAR=value
    ...
    perl program
    ...
    perl program

to set VAR for a series of runs.  I'm sure it will also have a
profile file in which you can place such settings so that they
get re-created every time you start up your computer.

There's probably some interaction you can do with the registry
to do the same withuot using cygwin, but I've managed to avoid
having to do serious work on a toy OS so I've never had to learn
its oddities.  (I've got enough oddities of my own to worry
about already. :-)
