An iffy start
An if statement is simple. if the day
is Sunday, then lie in bed. A simple test, with two outcomes. Perl conversion
(don't run this):
if ($day eq "sunday") {
&lie_in_bed;
}
You already know that &lie_in_bed is a
call to a subroutine. We assume $day is set
earlier in the program. If $day is not equal to
'Sunday' &lie_in_bed is not executed (pity).
You don't need to say anything else. Try this:
$day="sunday";
if ($day eq "sunday") {
print "Zzzzz....\n";
}
Note the syntax. The if statement requires something to test for Truth. This expression must
be in (parens), then you have the braces to form a block.
