If you want to lock a variable to prevent it from being changed, use the Lock Symbols() function. (Lock Globals() is an alias.)
Lock Symbols( name1, name2, ... );
To release the lock and enable the global to be changed, use the Unlock Symbols() function. (Unlock Globals() is an alias.)
Unlock Symbols( name1, name2, ... );
Note: You cannot use Lock Symbols() to lock a namespace. Instead, use ns << Lock.
