That's correct, and as in the documentation. PCOPY has no effect, it has none in GW-BASIC either.
Edit: Sorry, I misread as LCOPY
, which as no effect, PCOPY
should do things.
Looks like this line could be the culprit: https://github.com/robhagemans/pcbasic/blob/cea2af624b4aa390d70dbaef106647867ac5a673/pcbasic/basic/display/display.py#L439
Thanks, that does it. Currently it's copying the destination page to itself, which isn't very useful ...

PCOPY
does not seem to have any effect.Problem
I used the program below to test double buffering. A white square should be moving across the screen until ESC is pressed. The program worked with PC-BASIC v1 but in v2 an empty screen is displayed.
Program

PC-BASIC version: 2.0.5 Operating system version: Windows 10 64bit
