ps.map

[Alicia Palacios]

Hello,
I am trying to use the ps.map command, but when I attempt to run the
command I get the error :
(ps.map) was killed on a kernal access, at pc 0x40f174
Bus error(coredumP)

Does anyone know the source of this problem?  I set up the a device 
in the ps.devices directory following the notes in ps.select.  The
file was IBM_4019 and contained:
level:2 page width: 8.5 page height: 11.0 top margin: 0.5 bottom margin: 0.5 lef
t margin: 0.5  right margin: 0.5 resolution: 300

Thanks
