Do they use memory? I've to know this because i'm planning to use alot.

They're only used by the compiler.

Here is a lot of useful information for you: https://sampforum.blast.hk/showthread.php?tid=166680

Well yes.

Код:

#define VALUE 1

new getvalue = VALUE;
if(getvalue == 1)
{
    //the value is 1
}

The defines themselves don't use memory, as they're 'replaced' at compile time.

For example:

pawn Код:

#define VALUE 5
if(VALUE == 5)

Would, after compile, become:

pawn Код:

if(5 == 5)

I recommend you read the PAWN language guide.
