% ==================================================================
 
%  This deceptively simple code module causes ERROR #24, FATAL SYSTEM
%  ERROR at 0X51B976 on the HP Adobe PostScript Cartridge.
 
%  The module runs just fine on the NTX, LW+ and 820.
%  See SPOTDOTS.GPS GEnie PSRT #147 for a more detailed use example.
 
%  Apparently the translate and scaling is needed.
%  The blowup goes away when -stroke- is replaced by -fill- or -newpath-
%  -save- and -restore- bracketing does not help.
%  Does it with 4 megabytes, independent of jamrecovery state.
 
%  Cartridge recovers on hard reset or power down.
