Thank you

Hi all. Can a function return multiple values (comma separated) ?

return(1,2)

Or is it nonsense? :)) I just need to specify lot and order price. It's not rational to write two functions for it.

The function can return a value in the parameter passed to it by reference &

Where can I read more about it? I can't find it in the documentation here on the site. Thank you very much in advance.

You can pass data between different functions of one programme through global variables.
The number is unlimited.

Formally, it cannot. I.e., the function returns one value, but it may return a structure or a class (which is the same thing). Unfortunately, in MQL4 it is impossible, except for returning a structure that fits into 4 bytes (int). Then the information can be extracted using bitwise operations. Also you can experiment with DOUBLE and STRING.

In this case, the function modifies the parameter. Only returns the result in return.

You can alsochop an int into pieces using division (/) and remainder-of-division (%) operations

It's easier to return a string and then parse it, you can put a lot of information there :)

This is the same but through the ass. Piecewise operations are primary. They are faster.

STRING is promising, butDOUBLE is doubtful.
