Line Mode

Line mode supports line-by-line transfers of data to and from a terminal buffer. Line mode transfers are recommended for programs requiring a simple transfer of unformatted data, independent of terminal type. Line mode supports synchronous read and write operations and asynchronous write operations.

Note: While a line mode I/O session is in progress, only line-mode requests can be issued; basic mode and mapping mode requests ca CAuse unpredictable results.

By using line mode terminal management statements, you can:

Initiate a line mode I/O session
Write a line of data
Read a line of data from the terminal screen
End a line mode session
