I have 3 questions.

In the PDF "Implementor’s Guide", let's take LOAD.pri : pri = PRI = [address]
It is mentioned :

Quote:

An item between square brackets indicates a memory access (relative to the data register, except for jump and call instructions)

So, his code in C is :

PHP код:

pri = *(data + address) 


1. My first question is : there is any difference between a "data register" and a "data segment" ?

2. My second question is based on the tests I made.
I know when I declare a variable, her value is stored in memory, but we don't have acces to it easily, because I thought that it was only necessary to rely on the semantics.

Example : If I declare a variable named "myVar" with the value 41566421 and I want to get her address in the memory :

PHP код:

#include "a_samp"
main()
{
    new 
        myVar = 41566421,
        globalAddress;
    #emit ADDR.pri myVar
    #emit LOAD.I
    #emit STOR.S.pri globalAddress
    printf("0x%08x", globalAddress);
} 


It prints me : 0x027A40D5
Edit : Logic, 0x027A40D5 in decimal is 41566421... my bad

But the real address is among these :


If there is a difference in my first question, what data is use in the p-code LOAD.I ?
Otherwise : why it doesn't print me the good address ?

I looked the code in y_amx, and I see a semi-constant "AMX_REAL_DATA" initializes with some manipulations.

3. Is it better to use the p-code STACK twice or once in such cases ? :

PHP код:

#include "a_samp"
main()
{
    new 
        string[] = "Dutheil";
    #emit ADDR.pri string
    #emit PUSH.pri
    #emit PUSH.C 4
    #emit SYSREQ.C print
    #emit ADDR.pri string
    #emit ADD.C 12
    #emit PUSH.pri
    #emit PUSH 4
    #emit SYSREQ.C print
    #emit STACK 16 // fix the stack
} 


or ? :

PHP код:

#include "a_samp"
main()
{
    new 
        string[] = "Dutheil";
    #emit ADDR.pri string
    #emit PUSH.pri
    #emit PUSH.C 4
    #emit SYSREQ.C print
    #emit STACK 8 // fix the stack
    #emit ADDR.pri string
    #emit ADD.C 12
    #emit PUSH.pri
    #emit PUSH 4
    #emit SYSREQ.C print
    #emit STACK 8 // fix the stack
}
