IN:
C = number of bytes to copy (0 ... 255)
HL = local source pointer ($0000-$7FFF)
BDE = extended destination pointer
OUT:
Fc = 0 always
Registers changed after return:
A.BCDEHL/IXIY same
.F....../.... different |
...
Bank boundary crossing of destination is automatically handled, if number of bytes to read passes between to banks then B is incremented (typically when writing contents from a File Entry on a File Card).
...
The HL source pointer has to be in segment 0 or 1. The call does not work if the source pointer defines memory in segments 2 or 3.
