|  Problem to the BASIC listing, probably putting memory space to numeric variables with CLR
Hello to all user's PLUS4 WORLD,
Here uder I have put a basic list for C= Commodore 16, but when I do RUN, the
programm does not work, I think that it have need of memory with CLR, and
perharps of the POKE, that I not know. Can you help me, please??

I am not sure, but this {home} {down} are not ment to be written like this out, but this could be actual keystrokes on the c16 when typing the listing....

I just tried to import it into Yape.
It produced error at all lines with
PRINT"stuff";SC
when replacing it with
PRINT"stuff"SC
the error is gone. So removing the semicolon helps (but a "stuff",SC also does work)
then it does print the score. I am no Basic crack at all, just tried to import the lines.. Perhaps that ; is only a problem on my machine..
Btw. In Yape a right mouse click can paste the whole file from the clipboard.
EDIT: George has a working listing.. Seems like the ";" is a different character in yours and in Georges listing :)

The new code. And yes, {home} means the home button pressed in " mode.
I made some improvements in the subroutines, and added some basic time counting function.

Hello to all Users's plus4,
I have fixed lines with CHAR,0,1,STR$(SC) and add line 20 for INIT RAM MAPPER,
but I don't know if I well done.
The line 20 need for do space in RAM for numerical variables in theory.

If you need, then use the FRE(0) command in the code, it deploys a garbage collection and free some RAM.
I used it repeatedly in the Evader (Kerülő) and it worked.
Like this:
230 FRE(0):GETK$

Hello Verona,
Are you from Verona city italy?
I need not to see memory free RAM wth command FRE(0), then know already, but I need
of set to have more memory on numeric variables.
I hope there is some expert user:
POKE55,240:POKE56,55:CLR

No, I am a Hungarian. But I liked that word. (And name. And I like the Italian culture.)
That pair of command is set $37F0 to the top of memory used by BASIC. ( Default is $4000, so actually, that will do no good. ) The STREND pointer is at POKE49 and POKE50 it is also the free memory's start adress, and here's the string memory's bottom (FRETOP) at POKE 51-52, variable's start address is at POKE 45-46.
Maybe it helps. But nowadays I am only coding in assembly. Much better.
FRE(0) is triggering garbage collection, this frees some unused RAM. It's not equals with PRINT FRE(0)!!! If you use variables with much calculations, you need this!
Likely, if you take out all of the FRE(0) commands from my BASIC game, Kerülő (Evader), the game will crash after a while. With that, it works, I didn't use POKEs, like these.
Dont use that POKEs of yours on a C16, rather integrate just this into your code and try it.
230 FRE(0):GETK$

Hello Verona,
Okey, I will use this:
230 FRE(0):GETK$
Therefore I can to use of the POKES with address: POKE51,byte:POKE52,byte and
POKE45,byte:POKE46,byte for expansion memory mapper variables numeric?
if I will use very variables numeric ??
See you later and thank you very much

Hello Verona,
Listen!!!:
I tried to do 230 FRE(0):GETK$ but not work!! The BASIC C=16 he gives me ERROR !!
To this point, what type of POKE I must put? Or It has need of a routine in code machine??
See you later & Thank again
