[plt-scheme] I hate to bother the list with such a rudimentary question... but!

I think you're expecting behavior as you might get from "write-byte", 
but instead are getting something quite different from "write."

 > (write #x4d)
77
 > (char->integer #\7)
55
 > #x37
55

(write 77) is writing the Scheme expression "77" to the file in a format 
to be read by "read". It wrote two characters--both '7's--to the file.

I imagine the relevant references in the Help Desk might help clarify 
the behavior of "write", "read", and "write-byte".

Someone may end up chiming in with a more precise answer, but that's a 
quick response to get you started, I think.
