script question

I'm using solaris and i have an old script that an ex employee wrote but i can't seem to get it working. well is just one part of the script

if ($?MC_PROD_DIR == 0) setenv MC_PROD_DIR $HOME/PRODUCTION
source $MC_PROD_DIR/scripts/localenv

** i understand what this part of the script is trying to do, its trying to make the variable MC_PROD_DIR be equal to $HOME/PRODUCTION. I don't understand what the "question mark" does. i guess what would be the difference if the "question mark" wasn't there

NAME
service - run a System V init script SYNOPSIS
service SCRIPT COMMAND [OPTIONS] service --status-all service --help | -h | --version DESCRIPTION
service runs a System V init script in as predictable environment as possible, removing most environment variables and with current working directory set to /. The SCRIPT parameter specifies a System V init script, located in /etc/init.d/SCRIPT. The supported values of COMMAND depend on the invoked script, service passes COMMAND and OPTIONS it to the init script unmodified. All scripts should support at least the start and stop commands. As a special case, if COMMAND is --full-restart, the script is run twice, first with the stop command, then with the start command. service --status-all runs all init scripts, in alphabetical order, with the status command. If the init script file does not exist, the script tries to use legacy actions. If there is no suitable legacy action found and COMMAND is one of actions specified in LSB Core Specification, input is redirected to the systemctl. Otherwise the command fails with return code 2. FILES
/etc/init.d The directory containing System V init scripts. ENVIRONMENT
LANG, TERM The only environment variables passed to the init scripts. SEE ALSO
chkconfig(8), ntsysv(8), systemd(1), systemctl(8), systemd.service(5) Jan 2006 service(8)
