You can only perform result field I/O using a DS if you want to use a file in a subprocedure. So your ExFmt should look more like:

ExFmt EMail1 EMailDS;

Where EMailDS is defined with LikeRec( EMail1 : *All );

Reason for this limitation is that the compiler folks wanted to avoid having to implement essentially obsolete features such as I and O specs with subprocedures.

Thank you in advance for any advice!

I know that as of 6.1 physical files can be defined locally within a
sub-procedure, but is there no way to define and use a display file within
a sub-procedure?

I'm attempting to make a sub-procedure (called ChrGetEmail) that prompts
the user for an Email address. It could be used something like this:

myEmail = ChrGetEmail;

Here is a basic version of the code that I'm attempting to implement with
no success:

______________________________________________

PChrGetEmail B Export

FEMAILFM CF E WORKSTN InDDS(DSIndAra)

DChrGetEmail PI 100A Varying

//Local Variables

DDSIndAra DS

D F3 3 3N

DOutput S 100A

/Free



DoU F3 = *On;



ExFmt Email1;



If F3 = *On;

Leave;

EndIf;



If EmlEmail = *Blanks;

EmlError = 'Blank Email';

Iter;

Else;

If Not ChrValEmail(EmlEmail); //Second Sub-Procedure to Validate
Email

EmlError = 'Invalid Email Addres';

Iter;

Else;

Output = EmlEmail;

Return Output;

EndIf;

EndIf;



EndDo;



/End-Free

PChrGetEmail E

______________________________________________


When compiling this code, I get the error messages that none of the
variables defined within the WORKSTN display file are defined. Is there
another way to do this, or is this functionality not supported?

Thanks again for your time!
