Flow Control
Conditional Block
- Perl provides basic IF-ELSIF-ELSE conditional syntax
- Statement blocks delimited by "{ ... }" pair
if ( $colour eq "red" ) {
print "hot\n";
} elsif ( $colour eq "blue" ) {
print "cold\n";
} else {
print "warm\n";
}
- Notice the spelling of elsif...
- Notice no "then" keyword
