meta Meta language released

[zbyti]

Now I try emulate PEEK and POKE without assembly.

[zbyti]

If I want to write in ASM I know MADS essentials

 

I try to loop 10 [] etc.

 

write/line always ends with "repeat until keypressed" and so on.

 

I must wait, to early for me

Those are primitive, you have address definitions.

That is repeat in Meta, like in Logo.

That is not write/line, Meta does that on a DOS with a menu to enable you to read the output.

[zbyti]

OK. I try something one more time.

Site works here.

[Kaj de Vos]

Does the Meta website work for you?

[zbyti]

Not always.

The API is the same server, so if you have an unreliable connection with the site, it would also affect the API.

[zbyti]

yes. but compiler don't know that and communicate: 

Result is in file program.xex

 

ok. now works again.

[Kaj de Vos]

Yes, I saw it, that's odd.

 

cURL will be replaced, anyway.

Interesting:

 

count: 10

repeat count [write/line count: 10 - count]

write/line "end"

 

count: 10

repeat count [write/line count: 10 + count]

write/line "end"

count: 10

repeat count [write/line count: count + 1]

write/line "end"

 

count: 10

repeat count [write/line count: count - 1]

write/line "end"

[Kaj de Vos]

That's correct, count is not used as the counter variable.

[Kaj de Vos]

If you want that, use

for count 10 []

 

[zbyti]

and now?

 

count: 1000

repeat count [write/line 1000 - count]

write/line "end"

Correct again, but now you have a 16-bit counter instead of 8-bit.

but why 8-bit counter produced 0,10,0,10... and 16-bit correctly only 0?

[zbyti]

count: 10

repeat count [write/line count: 10 - count]

and

count: 1000

repeat count [write/line count: 1000 - count]

are not the same?

[Kaj de Vos]

Actually,

count= 10

would give you an 8-bit loop.

count: 10 - count

is different from

no?

[zbyti]

Why if I subtract 10 from 10 I have alternating result and if 1000 from 1000 is still 0.

 

I don't get it, the counter VARIABLE doesn't overlap and it's still not 0 in the first case.

 

--- EDIT ---

 

I understand repeat has its internal counter, I ask about MY variable.
