Setting session name when calling screen from script

[bradley . schrag]

I'm calling screen from a script and
want to set the session name based on run-time parameters. So I'm using
a command similar to:

VARNAME=FOO
screen -S $VARNAME 

Screen seems to just skip the variable.
Is there a way to persuade screen to expand $VARNAME to FOO? I'd rather
not have to build a case statement and hardcode every possible option.

Screen version 4.00.02 (FAU) 5-Dec-03
AIX 5.3

TIA
Brad
