The secret is in the regular expression you use to split upon. I'm thinking zero-width positive look-ahead assertion but that's just me. Documentation is available at perlre and perlretut. If you're just starting out, perhaps you should check out perlrequick for an overview. But to answer your question:

#!/usr/bin/perl -wl
$,=$";
print split/(?=[A-Z])/,"ThisString";
print split/(?=[A-Z])/,"SomeOtherString";
__DATA__
output:
This String
Some Other String

Hope this helps.

Updated: Just realized that I forgot to set $,. If not set as it is above, then the output would not have had spaces.
