pub const SSA: ControlFunction<'_>;Expand description
Start of Selected Area.
SSA is used to indicate that the active presentation position is the first of a string of character positions in
the presentation component, the contents of which are eligible to be transmitted in the form of a data stream or
transferred to an auxiliary input/output device.
The end of this string is indicated by END OF SELECTED AREA (ESA). The string of characters actually transmitted
or transferred depends on the setting of the GUARDED AREA TRANSFER MODE (GATM) and on any
guarded areas established by DEFINE AREA QUALIFICATION (DAQ), or by START OF
GUARDED AREA (SPA) and END OF GUARDED AREA (EPA).
ยงNote
The control functions for area definition (DAQ, EPA, ESA, SPA,
SSA) should not be used within an SRS string or an
SDS string.
