IBM System/34 And System/36 Screen Design Aid
Screen Design Aid (System/34 and System/36) (SDA) is a utility for the IBM System/34, System/36, System/38, and AS/400 (iSeries) midrange computers.
This article refers to the S/34 and S/36 implementations of SDA. S/38 and AS/400 use a different SDA with different syntax and characteristics. See the AS/400 article for more about these midrange computers.
SDA stands for Screen Design Aid. Programmers can use SDA to create menus, display formats, or WSU skeleton programs.
IBM midrange computers utilize display stations to present information and to accept information and control from computer operators. A display station is an input/output device consisting of a monitor and a keyboard.
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.

Famous quotes containing the words system, screen, design and/or aid:
“Human beings are compelled to live within a lie, but they can be compelled to do so only because they are in fact capable of living in this way. Therefore not only does the system alienate humanity, but at the same time alienated humanity supports this system as its own involuntary masterplan, as a degenerate image of its own degeneration, as a record of people’s own failure as individuals.”
—Václav Havel (b. 1936)
“Western man represents himself, on the political or psychological stage, in a spectacular world-theater. Our personality is innately cinematic, light-charged projections flickering on the screen of Western consciousness.”
—Camille Paglia (b. 1947)
“You can make as good a design out of an American turkey as a Japanese out of his native stork.”
—For the State of Illinois, U.S. public relief program (1935-1943)
“There exists in a great part of the Northern people a gloomy diffidence in the moral character of the government. On the broaching of this question, as general expression of despondency, of disbelief that any good will accrue from a remonstrance on an act of fraud and robbery, appeared in those men to whom we naturally turn for aid and counsel. Will the American government steal? Will it lie? Will it kill?—We ask triumphantly.”
—Ralph Waldo Emerson (1803–1882)
