I looked thru a bunck of lisp books in our library, as I couldn't
find *one* with a section on how to program with modified readtables. 

I want to read in some data files that could probably be read in as 
lisp objects, except for a couple of characters that the lisp reader
would choke on in the wrong context ( "#", ":", "=", "," ). 

Any hints, references, or examples on how to do this ? 

The readtable maps from characters to WHAT ? 
( i.e. what are the valid entries ? functions, Nil, ??? ) 


[ Most of the ancient LISP books I read long ago ( and promply forgot! :-)
 all had chapters on the lisp reader and the readtable. Has this
 programming idiom gone out of style, or has it just been crowded out
 by new chapters on CLOS?  ] 

[ Oops: I just looked in CTLT and found some info - probably enough to
 figure out my simple problem above - but I'ld still like to see a 
 more complex example, as well as the above question on style. ]
