Use the PUTLINE macro instruction to prepare a line and write it to the terminal. Use PUTLINE to put out lines that do not require immediate response from the terminal; use PUTGET to put out lines that require immediate response. The types of lines which do not require response from the terminal are defined as data lines and informational message lines.

The PUTLINE service routine prepares a line for output according to the operands you code into the list and execute forms of the PUTLINE macro instruction. The operands of the macro instruction indicate to the PUTLINE service routine the type of line being put out (data line or informational message line), the type of processing to be performed on the line (format only, second level informational message chaining, text insertion), and the options requested.
