TTWRITE(channel,buffer,<size>)

channel: is the channel variable returned from the TTOPEN function.
buffer: is the character variable, character literal, or an expression that contains the data to be written.
size: is an optional numeric variable, numeric literal, or expression that specifies how many characters to write from buffer. If you do not specify size, the entire buffer is sent, including any trailing blanks.

Details

If the TTWRITE function executes successfully, the return value is 0. Otherwise, the return value is the OpenVMS error code that indicates why it failed.

The TTWRITE function does not supply any carriage control. You must insert into the buffer any carriage-control characters that you want.
