Question 1:
First, if I'm printing a string and the value of a calculation of 2 variables, as in:
print "The average is $total/$count";
...how can I do it so that the value of the calculation shows up?? Right now I'm getting something like:
The average is 60/9
Just take the calculation out of the quoted string.
print "The average is ", $total/$count;Do I have to use PRINTF??? In fact, while we're on this subject, how can I format the value so that it only has two decimal places?
That you can do with printf.
printf "The average is %.2f", $total/$count;Question 2:
What are these NEXT, UNLESS and LAST statements? In my whooping 1 week of PERL, I haven't yet come across these statements. I'd like to learn. Can you suggest a good place for looking up PERL syntax/statements?
Type perldoc perltoc at your command line to see the table of contents for the Perl documentation. For the loop control statements, see the "Loop control" section in perldoc perlsyn.
