KEYP
KEY?

A predicate that outputs TRUE if there are more characters to read from the read stream. If the read stream is a file, then KEYP is equivalent to NOT EOFP. If the read stream is set to the Commander, then KEYP always outputs TRUE.

KEYP is provided for compatibility with other Logo environments. The traditional semantics of KEYP are not appropriate to FMSLogo's graphical environment.
