Check whether your terminal emulator supports or can be modified to 
support the DECterm DECSWT (Set Window Title) and DECSIN (Set Icon 
Name) sequences.

$  esc[0,7] = 27
$  fulldevnam = F$Edit(F$GetDVI("TT","FULLDEVNAM"),"UPCASE,COLLAPSE")
$  write sys$output esc+ "]21;" + fulldevnam + esc + "\"
$  write sys$output esc+ "]2L;" + fulldevnam + esc + "\"


Again, process names are labels. Like the implementation of event flags 
and the scaling and combination limits that are awaiting app developers 
in less-trivial cases, process names have a few surprises waiting when 
used in an application program for not-informational purposes.
