Does the method need to return a Boolean? You might return 0 or '0' for
success, or another integer, or character containing an error
identifier. You might even return positive values for informational
messages, negative values for errors.

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.
