Hi Brian

PROMPT_FMT has data on line 22 which means it over writes the information
from MSG on line 21.

OVERLAY applies at the line level.

Subject: Displaying Error Messages - Problem


Hi All,



In my RPG code, I have this:



If %trim(pqcat) ='';

  MissingCat = *ON;

  Message = '        Please enter a category';

  write Msg;

  Exfmt prompt_fmt;

  Eerror = *ON;

endif;



When this code executes, and a category is not entered, it will turn on
the indicator to highlight the field, but it will not display the
message.



However, when I change the code to this:



If %trim(pqcat) ='';

  MissingCat = *ON;

  Message = '        Please enter a category';

  write Msg;

  Exfmt PQCTRL;

  Eerror = *ON;

endif;



The message will appear along with the field being highlighted.  Can
someone explain why one way it will display, but the other way it won't?
Here's the DDS code that controls it:
