Implementation Defined Options
- encoding of keyboard events (
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
.
- duration of a system clock tick:
- System dependent. With respect to
MS
, the time is specified in
microseconds. How well the OS and the hardware implement this, is
another question.
- repeatability to be expected from the execution of
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.
