The :s (substitute) command behaves a little bit 
different to that of vi. If you type a command like this in vi   
:s/XXXX/UU/ then the four XXXX's are
replaced by
two UU's. This means, the file size decreases and all characters after
the replacement are moved to another position in the file. Since bvi
does not move characters, only two XX's are replaced by two UU's and
the third and fourth X still remains in the file.Another example:
 
:0,500s/Taste\0/Key\0/RETURN
 
This command replaces within the first 500 bytes of a file the 0 -
terminated ASCII string "Taste"
with the 0 - terminated
string "Key". After the substitution
you will find a 
character sequence "Key\0e\0" in the file.CAUTION: If the replace
string is longer than the find string, additional bytes are overwritten!
 This behaviour will not be changed by setting the
:set memmove option!
 
Of course you can do also binary substitutions, similar to the search
command. The ability of remembering patterns like \(pattern\)
is currently not implemented.
