title: CLS / CLRSCR
description:
        CLS is the shorthand for CLRSCR or CLEARSCREEN.
        Some implementation had even chosen to add a dot
        before to flag that they do in fact output sth.,
        probably an escape sequence.

        The term CLS is used in MPE/ProForth, pfe and win32for.
        gforth/bigforth uses PAGE to clear the screen and set
        the cursor to the homeposition. (paysan)

example-implementation:
        gforth does...
        : PAGE ESC[ ." 2J" 0 0 at-xy ;

standard-note:
	PAGE is an ANS94 standard word - it implies somewhat like
        a \f = formfeed character being printed to a hardcopy
        terminal. Programs should probably use this word.

cls-note:
        CLS happens to be more intuitive and easier to remember.
        The term PAGE could mean to just emit a few lines to
        come to the next PAGE while CLS does make it explicit
        that previous lines are erased rather than scrolled up.
