I will be glad to see your current version -and- would be happy to
see the final version also...  My net address is below.  Feel free
to send me a copy when you get the time unless you're planning to
post it to the .binarys. or .source. newsgroups...

Excuse me, but this doesn't sound like a bug...  If you take a look at
K&R page 94, "In fact, any reference to an array is converted by the
compiler to a pointer to the beginning of the array."  This means you're
taking sizeof a pointer, which is in fact 4...(Remember, in C a string
is no different from a null terminated array of characters.)

  Sure you didn't intend to use strlen("anystring") instead?  That, would
return 9 as the length of the string....

This doesn't work in -most- librarys...  Try %* and using a negative
argument instead....
