[ale] Environment Variables

[dhamm at itserve.com (David Hamm)]

I'd like to have a way to set my default printer on the fly from a child
process (i.e. a program that sets the default printer ).  If I set the PRINTER
environment variable to something like this, "PRINTER=`cat ~/defprinter`", the
environment variable only gets set at the time the variable is declared.  Is
there a way to have the variable set each time it is accessed?
