Screen Input APIs
The screen input APIs allow you to read data and other information from the
screen. This includes field data, screen attributes, and the cursor address.
The screen-input interfaces correspond, either directly or indirectly, to the
5250 data stream read commands.
The screen input APIs are:
- Get AID (QsnGetAID) waits for an AID-generating key to be pressed.
- Get Cursor Address (QsnGetCsrAdr) gets the current cursor address.
- Get Cursor Address with AID (QsnGetCsrAdrAID) gets the current cursor address after an AID-generating key is pressed.
- Put Input Command (QsnPutInpCmd) issues a supplied read command.
- Read from Invited Device (QsnReadInvited) performs a read from invited device on a display that has already been invited.
- Read Immediate (QsnReadImm) reads the contents of all input fields on the display without requiring an AID key to be pressed.
- Read Input Fields (QsnReadInp) reads the contents of all input fields on the display requiring an AID key to be pressed.
- Read Modified Alternate (QsnReadMDTAlt) reads the contents of all modified fields on the display, alternate form, requiring an AID key to be pressed.
- Read Modified Fields (QsnReadMDT) reads the contents of all modified fields requiring an AID key to be pressed.
- Read Modified Immediate Alternate (QsnReadMDTImmAlt) reads the contents of all modified fields on the display, alternate form, without requiring an AID key to be pressed.
- Read Screen (QsnReadScr) reads the contents of the screen without requiring an AID key to be pressed.
