Screen Design Aid (SDA) is a utility for the IBM System/34 and System/36 midrange computers. Programmers can use SDA to create menus, display formats, or WSU skeleton programs. The System/38, and IBM i platforms also have a utility Screen Design Aid, but it syntax and functionality is different.
S/34 and S/36 applications usually involve the operator to a critical degree, whether accepting the bulk of input through display stations or controlling them. Computer programs may utilize unformatted or formatted input, and this is where SDA applies.
