allow potential special characters '@' and '$' in system call

[wong_powah]

I want to change a system call to allow potential special characters
'@' and '$'.
This work for regular character in $PASSWORD.
$rc = system("/usr/local/bin/mylogin -i 1234:5678 -s 3 -o -p $PASSWORD
1>login.out 2>login.err");
How to change it to a form that allow potential special characters '@'
and '$' in $PASSWORD?

I tried this, but it does not work:
$rc = system "/usr/lunasa/bin/salogin", "-i 1234:5678 -s 3 -o -p
$PASSWORD 1>salogin.out 2> salogin.err";

print "rc $rc";

rc 65280
