I am hoping the members of this group can help out with a postscript
newbie question.

I have a need (for reasons too hilarious to go into here) to
post-process Postscript output files from an application before they
go to print.  What I need to do is find a certain byte value (0xBA)
and change it to print as a Registered Trademark symbol.  I think the
best way to do this is to insert an escape sequence into the operand
for the ( ) show command such that the magic byte becomes a
'registered.'

I am having the devil's own time finding the right reference to how
this would be constructed.

As a follow-up question, since I obviously need it, where o where is a
decent online PS tutorial???

Thanks!
