cc65 : i want to leave this if if it is true.

[funkheld]

Hi good afternoon.

i want to leave this if if it is true.
how does that work please

with break I also leave the main loop and I don't want that.

Thank you.
greeting

Code: Select all

ip=y*22+x+scradr;
if (PEEK(p)==1)
{
.......
}	
POKE(p,0);
x=x+1;
p=y*22+x+scradr;
POKE(p,32);
x=x-1;
.........
}

can you post the whole program, that extract doesn't make much sense

what do you mean by "leave this if"?

Hi good afternoon.

I didn't want to take "break".

is there anything else for this?

Thank you.

As beamrider already wrote, it is not possible to infer - from your question and the source fragment you give - what the actual problem *is*!

We're talking about *basics* of structured programming here: if you have a code sequence S1, which shall be executed upon a predicate P being true, another code sequence S2, which shall be executed upon same predicate P being false (i.e. not true), have some code sequence S3 which doesn't depend upon P but is supposed to be executed before either S1 or S2, and finally have some code sequence S4 which also doesn't depend upon P but is supposed to be executed after either S1 or S2, you write this as follows:

Code: Select all

S3
if(P)
  S1
else
  S2
S4

... with S1 and S2 each either a single statement ended by a semicolon, or a compound statement enclosed in curly braces {...}, where the closing brace is *not* followed by a semicolon.

In C, the break statement does not operate upon the "if(<condition>) <statement> else <statement>" structure as given above, but it terminates the innermost surrounding loop (for, do, while) or switch statement.

he thanks for hlep.

This post here also in response to many other similar inquiries you're doing here in Denial:

he thanks for hlep.

Please follow up with a post how it helped you in that particular case.

Just getting a meagre "thanks" is not sufficient at all, if no one else but you gets some information from it!

This is a public forum, sharing of knowledge is a very important aspect of it, but at the moment you're asking for far more than what you're giving back.
