binary split

[Daniel Hitt]

Is there an analogue of the split command that instead of working on
the basis of lines works on the basis of characters?

That is, one would type
splitPrime -200000 afile z
and afile would be split into chunks of 200000 bytes in files named
z00 z01 z02 . . . (the suffixes being a function of how large afile is).

Of course, one can easily write such a program, but i'd prefer to use
a standard tool if there is one (because i can use it in scripts on
different machines, etc.).

If this is an RTFM question, please give me the section and command name.

Thanks for any info anyone can provide.
