You are in fact wrong. It is much simpler than that. The signon
program reads a screen buffer with your user ID and password
you just typed. The contents of that buffer hangs around until
signoff or another signon (when it will contain yet another
password !). A general principle of secure working is the
erase the contents of all buffers and variables as soon as
they are no longer needed. IBM violated that simple principle.
