LSVSORT removes the first PW= even if it was NOT a store function.  If a
user is added, or subscribes, or whatever else causes LSVSORT to be invoked,
LSVSORT goes ahead and deletes the first line if it is a PW= regardless
of what function did this.
 
Circumvention:  Do not place the real PW= on the first line.
 
Suggestion:  Move the PW= deletion to the code for the store function,
rather than have LSVSORT do it.  Having LSVSORT check to see what function
is being performed violates the idea of modular coding.
