comments
KMoveDataBuf allows Interpreted BASIC users to transfer data to/from an internal
buffer (not easily accessible from BASIC) to/from a BASIC user array. You would
normally use this Call after a KIntStart operation ends.
Refer to the examples below for steps on how to transfer the first
100
A/D samples
from an internal buffer to a BASIC array. Note that the internal buffer at &H8000:0
was
used
to acquire data in a previous A/D operation.
If the Destination or Source Buffer are DIMensioned arrays, the Segment value
should be set to &HFFFF.
