m=SYS(5)+CURDIR()+"WEB_BACKUP.ZIP"

n="mailto:brandini2000@bol.com.br?subject=Web_Backup Envio de Arquivos para Tratamento&body=" ;
+ "Anexe o arquivo " + m + " ao seu e-mail por favor... " +CHR(13) + chr(10)
n= n + "Web_Backup *.dbf *.ini *.log (Gerado Automaticamente)" +CHR(13) + chr(10)
n= n + " pasta de trabalho = " + SYS(5)+CURDIR() +CHR(13) + chr(10)
