EKEY): ¶Keys corresponding to ASCII characters are encoded as ASCII
characters. Other keys are encoded with the constants k-left,
k-right, k-up, k-down, k-home,
k-end, k1, k2, k3, k4, k5,
k6, k7, k8, k9, k10, k11,
k12, k-winch, k-eof.
System dependent. With respect to MS, the time is specified in
microseconds. How well the OS and the hardware implement this, is
another question.
MS: ¶System dependent. On Unix, a lot depends on load. If the system is lightly loaded, and the delay is short enough that Gforth does not get swapped out, the performance should be acceptable. Under MS-DOS and other single-tasking systems, it should be good.
