A parent does not inherit from its child. Whatever you set inside the
awk program is unknown outside it.

Your grep is superfluous, BTW.

Try this:

eval `ps -ef | awk -v user=$LOGNAME '
$1~user && $8~"/usr/lib/merge/xcrt" {print "pid=" $2 " pseudo=" $6}
'`
echo PID is $pid and PSEUDO-TTY is $pseudo
