Anyone can create HPCIERRnnn:
  :setvar HPCIERR!HPPIN, value
 
HPPIN is an integer CI predefined variable that contains your PIN.
 
However, 1) you probably should not begin your own variable names with "HP"
and 2) doing this does not remove the window where Process A executes a command
and wants to test HPCIERR, while Process B clears HPCIERR just after
Process A's command executed but before Process A could check the result (or
could make a "local" copy of HPCIERR).
