MQL4 Language Most Recent Version is it updated beyond the tutorial on the mql4 websi

Hello, to whoever can help me. Your help will be greatly appreciated. I am kind of at a road block here.

I am studying the language mql4 from the website http://book.mql4.com/basics/functions. But when I type in a simple function (even if I type exactly as indicated from the tutorial) I get errors when I try to compile it. I am wondering if the tutorial may be outdated? Maybe there have been updates to the language since the tutorial was written?

Or maybe I am missing something.

This is an example of a simple function. That I get errors on.

int Gipo(int a, int b)
{
int c2=a*a + b*b;
int c=MathSqrt(c2);
return(c);
}

These are the errors that the compiler returns.

'(' function definition unexpected
'c2' variable not defined
'}' unbalanced paranthesis

I type the code exactly as indicated and modify it in every way that I can think of but still get errors. I have tried other more simpel functions as well and always get similar errors. Please Help! Its driving me nuts!

Thanks, Brian.

post all of it here. Sounds like you are missing a } somewhere but I can't tell without the entire code.

I hope this works and thanks for the help.

ok, now I see it.

the int Gipo is inside of the start function, you cannot declare a function inside another function you will get errors. Attached is a corrected version>

This is Great!! It works now. I see now that you can not declare a function inside of a function. However I do not understand the line you added inside the start function---int x = Gipo(4,6);

Please explain. I know I am a noob at this.

Also can you recommend any other sources for mql4 language for dummies? I am determined to learn this!

sure no problem.

That line actually calls the function you created called Gipo, then assigns the value it returns to the variable x. If you notice in Gipo you have a statement that says return(c). That is where the value of the calculation is being passed back to whatever made the call.

Attached is a bunch of lessons someone wrote on working in MQ4.

Ah yes that makes since. I should of seen that myself. I cant wait to review the lessons you attached.

It may seem trivial to you but this has been a great help. I hope you will be around in the future. Im sure I will have more questions. All the best to you!

Brian.
