~"y"- ~$         v
  <temp var for when char changes
format:
first,'n' and a newline.             :
a char then a                   v    _"n",v
number then a space continuously          9
example:                                  1
n                               >    v  ,+<
a5 b2
decoded:aaaaabb
the program is ended using   decoder
Ctrl-C on linux,or alt-f4
on windows.copy the output    >\v       encoder
of the program somewhere      ^_ $ v
to encode press y              :        > $11g:,  v
to decode pipe file in      >1-^   ~       v  +1\<
the output of the encoder   \  v<  $    ^     .\_^
starts with n,this is so    ^,:<\&~< _~:,>1>\:v>^
you can pipe it straight in              ^        <
                                              ~
the spaces seem to be a annoying thing        :
thanks to CCBI...if a interpreter dosen't     1
create them it's non-conforming and thus      1
the validity of this program is NOT affected  p-
