Perhaps something like this, you'll get the idea

Code:
trap clear EXIT
DIALOG=${DIALOG=dialog}
while :
do
  rfcval=$($DIALOG --title "RFC NUMBER" --clear \
          --inputbox "Please enter an RFC Number" 16 17 2>&1 >/dev/tty)
  retval=$?
  case $retval in
    0)
      case $rfcval in
        N/A|n/a)
          exit 0 ;;
        [!0-9])
          : ;;
        *[0-9][0-9][0-9][0-9][0-9]*)
          echo "RFC Number: $rfcval" >> $accessfile
          exit 0;;
      esac ;;
    1)
      exit 1;;
    255)
      rm -f "$accessfile" "$tempfile" "$sitefile"
      exit 1 ;;
  esac
done

NAME

SYNOPSIS

       tk_chooseColor ?option value ...?
_________________________________________________________________

DESCRIPTION

       The  procedure tk_chooseColor pops up a dialog box for the user to select a color. The following option-value pairs are possible as command
       line arguments:

       -initialcolor color
	      Specifies the color to display in the color dialog when it pops up. color must be in a form acceptable to the Tk_GetColor function.

       -parent window
	      Makes window the logical parent of the color dialog. The color dialog is displayed on top of its parent window.

       -title titleString
	      Specifies a string to display as the title of the dialog box. If this option is not specified, then a default  title  will  be  dis-
	      played.

       If the user selects a color, tk_chooseColor will return the name of the color in a form acceptable to Tk_GetColor.  If the user cancels the
       operation, both commands will return the empty string.

EXAMPLE

	      button .b -bg [tk_chooseColor -initialcolor gray -title "Choose color"]
