    I would have used "rot-13", but I'm *not* sure if folks know how to use that anymore...

    Bayl fbzr ?


    I wrote my own in asm;
    what a lookup table? much shorter:

    I use tr:

    $ more bin/rot13
    #!/bin/sh
    tr '[A-Za-z]' '[N-ZA-Mn-za-m]'

    Did I reply here? not sure
    I have implemented a barebones tr for DOS that accepts ranges, so rot13 jbexf. Luckily it also seems to work with or without the square brackets.
    100 bytes (no error messages, and barely any^w^w no syntax checking).
