Typographic errors are maddening; I make them all the time...
A drawback with online documentation is that you need to know the right
question and how/ where to ask it. The Search box of the Perl
Programming Documentation web site was able to find the substr function
given the subroutine name from the above error message (the part that
follows "&main::"):
http://perldoc.perl.org/search.html?q=subst
An advantage of good, printed books is that they have a Table of
Contents and an Index. Do you have the three books I suggested?
