//		   modificado para trabalhar tambem com tres campos dia mes ano
//		   prefixadas funções e variáveis para cal[nome]
//  
// Usage:  Adicione as seguintes linhas de código
//         // Carrega o componente na página
//
//         <SCRIPT LANGUAGE="JavaScript" SRC="PRCalendbr.js"></SCRIPT>
//

//
//         // Esta linha &eacute; usada em conjunto com um campo do formulario (myDateField) em um form (myForm)
//         // Substitua "myForm" e "myDateField" com os nomes do campo e do forms respectivamente
//         // Opcoes da janela ajusta tamanho, posicao, etc.
//         //
//         <A HREF="javascript:calSetDateField(document.myForm.myDateField);top.newWin = window.open('calendar.html','cal','dependent=yes,width=210,height=230,screenX=200,screenY=300,titlebar=yes');void(0)">

//      
//		Sintaxe geral:
//
//	calShowCalendar([*datainteira],[ dateformat],[*campodia],[*campomes],[*campoano]) 
//
//  Parametros omitidos, informar 'null'
//  Se Forem informados campodia, mes e ano, estes serao usados para montar dia inicial do calendario
//		e receberao valor.
//
//  *informar ao menos um destes = referencia a campo do forms onde depositar os valores.
// 
//        
// Arquivos necessarios:
//
//         PRCalendbr.js - Contem as funcoes JS para a construcao da tela de calendario
//
//		   calendar.html - frameset para abrir calendario. Desnecessario se utilizada calShowCalendar()
//
// 
// Arquivos acessorios:
//
//         calendar.gif  - Imagem para o link ao calendario
// 
//         yourPage.html - Pagina que fara uso do componente
// 
// Especificacao de formatos para o calendario
// (usados como macrosubstituicao em texto)

// mm      = Mes de  1 ou 2-digitos
// MM      = Mes 2-digit Month
// aa/AA   = Ano 2-digitos
