Can someone explain to me what these symbols do in the program? { }

Or tell me where to go to read about them...? can't find anything by just searching.

I'm just a newbie trying to teach myself to program in MQL4.

It's a BLOCK of code. read it like...


IF (bla bla) THEN

{

do all this

and this

etc

}


The curly brackets comes from the program language C, and MQL4 is very similar to the language C++, which origines from the language C.


So the curly brackets consists of a pair (a left and a corresponding right curly bracket). And everything in between is regarded as block of code.

 

In programming language Pascal a code block starts with BEGIN and ends with END

In programming language 'C' a code block starts with { and ends with }

And in the programming language Python mankind was finally freed from this annoying burden because the compiler can figure out on its own where a block begins and ends by simply looking at the indentation level.
 

I liked the N. Worth upgrade of Pascal to Modula II, not had the ocasion to look at his version of object programming in Oberon.
