SPH top-level constant

String const SPH

Set Page Home.

Representation: CSI n \x20 \x69

No parameter default value.

If the DEVICE COMPONENT SELECT MODE is set to PRESENTATION, SPH is used to establish at line position n in the active page (the page that contains the active presentation position) and subsequent pages in the presentation component the position to which the active presentation position will be moved by subsequent occurrences of FORM FEED (FF) in the data stream. In the case of a device without data component, it is also the position ahead of which no implicit movement of the active presentation position shall occur.

If the DEVICE COMPONENT SELECT MODE is set to DATA, SPH is used to establish at line position n in the active page (the page that contains the active data position) and subsequent pages in the data component the position to which the active data position will be moved by subsequent occurrences of FORM FEED (FF) in the data stream. It is also the position ahead of which no implicit movement of the active presentation position shall occur.

The established position is called the page home position and remains in effect until the next occurrence of SPH in the data stream.

Implementation

const String SPH = ' i';
