## NAME

CGI::radio - Make a radio button.

## SYNOPSIS

## ARGUMENTS

**name** The name of the radio button. Only one radio button with a given name may be selected at once

**val** The value of the radio button.

**set** If this is true, the radio button will start checked. Browser behaviour is undefined unless exactly one radio button out of each set begins checked.
