Register Repeats

• The registers can be used to record macros.
• To record a macro type q{reg}, and type the keystrokes you wish to record and then type q.
• To execute a macro type @{reg}.
• • You can use the {integer}@{reg} to execute it a number of times.
• For example:

qm/^sub<CR>4ly$/^{<CR>oprint "Entering <ESC>pa";<CR><ESC>q

• • Then typing @m will cause:

sub hello
{
    my ($x,$y) = @_;
    print (($x+$y,"\n");
}

• • to transform to:

sub hello
{
    print "Entering hello\n";
    my ($x,$y) = @_;
    print (($x+$y,"\n");
}

• • You can also type 1000@m and it will cause all the functions to be transformed.
