is decoded which results in a line number. Then the
cursor position is requested and the answer is decoded
which results in a line number and column number. The
cursor position is calculated based on the two results.

The Format Handler interfaces to Application software
(via System Call Monitor) and to the VDU handler in
the LTUX handler subpackage. For load of Formats the
File Management System is interfaced.
The application interface has been described in 4.1.7.2.3,
below the VDU handler interface is described.
4.2.1.7.1 F̲o̲r̲m̲a̲t̲ ̲H̲a̲n̲d̲l̲e̲r̲ ̲V̲D̲U̲ ̲H̲a̲n̲d̲l̲e̲r̲ ̲I̲n̲t̲e̲r̲f̲a̲c̲e̲
This interface is via a Data-connection and a Control
connection.
Basically all information to/from the VDU split flows
via the data connection and VDU handler control flows
via the control connection. An exception is for input.
The first output operation after an input request on
the data connection is assumed to contain the data
for the arm command.
4.2.1.7.1.1 D̲a̲t̲a̲ ̲I̲n̲t̲e̲r̲f̲a̲c̲e̲
Fields are output in IOC ̲RECORD ̲TYPE with the DATA
̲FLAG.
Cursor positioning, bell and clear split are output
in IOC ̲RECORD ̲TYPE with the CONTROL ̲FLAG.
Arm command is not in IOC ̲RECORD ̲TYPE
4.2.1.7.1.2 C̲o̲n̲t̲r̲o̲l̲ ̲I̲n̲t̲e̲r̲f̲a̲c̲e̲
The interface over the Control Connection is specified
in each case as of below:
Function Key input:
INIT ̲READ ̲BYTES issued to the Control Connection.
1 byte is returned (values as of FUNCTION ̲KEY)
Control output:
a) Subsplit select 1.byte SUBSPLIT ̲SELCT
2.byte (PRIMARY, SECONDARY)
b) Link split (secondary to primary)
1.byte SUBSPLIT ̲LINK
c) Data key enable 1.byte DATA ̲KEY ̲ENABLE
