CLS / CLRSCR
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:
: 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.
