No matter what I did I could nor get your code to work
Code: #include <spectranet.bas>
30 conn1 = SNETconnect(4 , "the8bitmud.zapto.org", 16384)
So I used bits of polomints code.
As you see my code is all over the place but works.

A bit confused on how to use the ip$ here
Code: Function FASTCALL SNETconnect(socket As ubyte, ip$, port As uinteger) As byte
Asm
pop hl ; ret address
pop de ; string containing the IP in CODE format. e.g. 10.0.0.1 = chr$(10, 0, 0, 1)

ardentcrest Wrote:Time for me to give up on this..... If you read the comment above (in the ASM source code) the IP must be constructed with CHR$(), like:
Code: REM 192.158.1.4
IP$ = CHR$(192, 158, 1, 4)
REM also...
IP$ = CHR$(192) + CHR$(158) + CHR$(1) + CHR$(4) ' This is equivalent but slower

I'm still having problems with your code  But I do now have some code that works.
Now I need help with this
I have this
Code: ASM
garbage2: defm 0
END ASM
How would I put a text string into garbage2 from basic. Would I have to poke each CHR code one by one, and how would I find the address if garbage2

How would I put a text string into garbage2 from basic. Would I have to poke each CHR code one by one, and how would I find the address if garbage2 If you have code that works, then it would be very useful to me to check if my routines are failing and why (no information last year, just reverse engineering, and little time...).
For the 2nd question, you can:
Code: LET a$ = "Hello World"
FOR i = 0 TO LEN(a$) - 1:
POKE @MyLabel, CODE a$(i)
DoSomething(...)
NEXT i
END : REM Prevents the program entering MyLabel zone

check my post. above its the dirty code 
so with that code if garbage2: was address 60000, would all the text go in just 60000 because I would like the code to do
H=60000
e=60001
l=60002
and so on....
PS I'm really getting in to the compiler in a big way. Must do a game with it
On a side note. this client will have to be like an IRC client with two boxes. one for the incoming text and one for the input, as there will be incoming text as you are typing, and that will start to get messy, and then incoming text box will have to scroll while the input box stays static. :?

To do that, you have to *ensure* there's enough room for the string you're allocating in the ASM space:
Code: LET a$ = "Hello World"
REM Poke all the string chars starting at address @MyLabel
FOR i = 0 TO LEN(a$) - 1:
POKE @MyLabel + i, CODE a$(i)
NEXT i
DoSomething(...) : REM OK, now this is OUT OF THE LOOP
END : REM Prevents the program entering MyLabel zone
MyLabel:
ASM:
garbage2:
ds 32 ; 32 bytes of space MAX!!
END ASM

Its slowly coming together. still need help.
In my print routine
Code: ld a, (v_sockfd)
ld de, **address of text**
ld bc, **length of text string**
ld hl, SEND
call HLCALL
How can I make this a function.
