What will be an ideal response?
In a Perl program, to go from one function to another, you simply call the function by entering the function name in your source code. In the following example, the &name_best_guitarist line branches the program to the sub name_best_guitarist function:
# Perl program illustrating the branching function
# Documentation is important
# Initialize variables
$first_name = "Jimi";
$last_name = "Hendrix";
&name_best_guitarist;
sub name_best_guitarist
{
printf "%s %s %s", $first_name, $last_name, "was the best!";
}
