Helpful answers to unhelpful complaint

[QSDDS]

Sorry but so much problems, i can't do anything

• no poke peek and call
• sound with only 2 parameters
• put and get not working with screen 9 (640x400 16 colors)
• can't read arrow keys : a$=inkey$ print asc(a$)
  and others and others
  With pc-basic 2.0.4 on raspberry pi 3B+ and raspbian

If something does not work, please file a bug report specifying what you did, what you expected to happen and what happened instead.
As it stands your message is "unusable" itself.

One example, sound does have four parameters in Tandy or PCjr mode, while GWBASIC's SOUND only has 2 parameters, so if you need those parameters you need to choose tandy/pcjr syntax See the documentation https://robhagemans.github.io/pcbasic/doc/2.0/#SOUND.

What is "not working" for PUT and GET in SCREEN 9? You are not giving any information.
What are you trying to do with arrow keys?

PEEK and POKE have very partial implementations as we're not emulating the whole PC, if that's what you need you need to look at a PC emulator and run GW-BASIC on it.

"And others and others" - what others? If something does not work, please report it, just saying "lots of things don't work" is extremely unhelpful.

@QSDDS The limitations with PEEK, POKE, and CALL are documented. Also the number of arguments of SOUND and the condition under which there are four of them.

I suspect you can read the arrow keys just fine and the ASC is the source of an illegal function call — that's because INKEY$ does not wait for a key to be pressed but returns with an empty string when there is no key to process, and ASC obviously has no way to turn nothing into a number. Again all documented.

Just in case your problem with GET, PUT, and SCREEN 9 is missing pixel lines at the bottom of the screen: mode 9 is 640×350 and not 640×400. Also as documented.

This small test programs works for me:

10 SL=32:SCREEN 9:CLS:FOR I=0 TO 15:CIRCLE (SL\2-I*0,SL\2-I*0),I,I,,,1:NEXT
20 DIM A%(SL^2\2+2):GET (0,0)-(SL,SL),A%:CLS
30 FOR I=0 TO 4:FOR J=0 TO 4:PUT (I*SL,J*SL),A%:NEXT:NEXT
