Separate buisness and display logic question

[David FOXWELL <David.FOXWELL@xxxxxxxxx>]

Hi all, 

A program displays 5 fields concerning a client's bank details. A procedure exists that accepts these details as a DS and checks each field. 

eg:


D CheckBankDetails...
D                    PI       N
D BankDetails                       likeds(refDS) const
D error                             like(refError)


 /free
	If BankDetails.AccountNumber <> etc
		error = 'etc..'
		return *off
	endif

	If BankDetails.BankCode <> etc
		error = 'etc..'
		return *off
	endif
/end-free

Caller : IF not CheckBankDetails ( DSBank );
		//Now what?
	   Endif;

On returning from this procedure, how can the display manager program position the cursor on the first incorrectly filled information using an indicator and DSPATR(PC)?



Thanks.
