The below excerpt from the manual explains the issue. I see where EXFMT can be used with a data structure so try that, I have never used it that way. See the manual for details on how the data structure must be defined.

"Files can be defined locally in subprocedures. I/O to local files can only be done with data
structures; I and O specifications are not allowed in subprocedures, and the compiler does not
generate I and O specifications for externally described files."

Subject: Sub-Procedures with Local Display Files?

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!
