Link
The two objects connected by the link are quoted in this section.
Data entry
Condition
Condition of the link: this can be a function key, or a condition which must be integrated as such in the 4GL source. It must thus be written with a syntax verification (Adelia Studio does not check out this syntax) to prevent any rejection during the compilation on AS/400.
The text is automatically set to upper case characters during the validation, except the text between quotes.
Optional entry.
Parameters
This field is used to enter parameters which condition or affect the link.

Enter/Create/Modify (validation)
The Enter button (in display mode) closes the dialog box.
