Size of Presentation Spaces

An emulator display session can be configured for a range of screen sizes from 1920 bytes (24x80 screen size) to 9920 bytes (62x160 screen size). Some EHLLAPI functions such as Copy PS to String (8) require the application to allocate enough storage to hold (possibly) the entire presentation space. The size of the presentation space for a given session can be obtained using the Query Session Status (22) function.
