ID DIVISION.
PROGRAM-ID. TFRTST.
remarks.
	TFRTST will display all or a portion of an arbitrary
	form on the screen so the programmer can determine
	if the form description is correct;

	The prompt for form name expects the full data file
	name for the form;

	The field-id is the same as in a call the TFRRD:

	0 indicates the whole form is displayed;
	-n displays section "n";
	n displays filed "n";

	after the requested portion of the form is displayed,
	a TFRRD is automatically done so that the attributes of
	the fields can be tested for correctness;

	Hitting carriage return for field-id will go back to
	the form-name prompt and a new form can be tested;

	Carriage return to the form prompt will cause TFRTST
	to exit.
