SETLINES()

Syntax:     SETLINES(<expN>)

Arguments:  <expN> corresponds to the number of lines on which the
            screen output should be based.

Returns:    A character string.
            This function will always return a null string.

Usage:      The effect of Ctrl-S can be simulated for commands such as
            LIST or DISPLAY via SETLINES().  However, there should
            always be an input command available in the instruction used
            for this purpose (see example).

Note:       Only the line shift symbols will be counted.  Use values less
            than or equal to 0 for <expN> to eliminate any stop.

Library:    CT1.LIB


--------------------------------- Example ------------------------------

Examples:   * The screen output should stop after 20 lines.

            USE date
            SETLINES(20)                && Stop after 20 lines
            LIST field1, field2, NULL(INKEY()).

            * The keyboard will be continuously queried by
            * INKEY(); the function NULL() will suppress the
            * return value of INKEY().
