Screen Formatting

The user interface of a Progress application consists of one or more windows, whose size and number affect the space available for frames. Depending on your environment, character or graphical, there are different factors to consider when you lay out frames.

There are two ways a terminal can handle screen formatting: spacetaking and nonspacetaking. A spacetaking terminal reserves a character position on both sides of every field for special screen display attributes, such as underlining or highlighting. A nonspacetaking terminal does not reserve character positions for special screen display attributes.

NOTE: Although UNIX supports spacetaking and nonspacetaking terminals, Progress supports nonspacetaking terminals only.
