Note location of semicolon.

Code

print "What is your name?\n";

Good Luck,
Bill

The lesson is that when you get a compile error on line n, you must look not only at line n but also at line n - 1 and also at the previous lines (sometimes the error is 10 or more lines above the line at which the compiler choked).

Code

my $name = readline STDIN;

That is normally written as:

Code

my $name = <STDIN>;

You can also combine it with the chomp statement.

Code

chomp (my $name = <STDIN>);
