Dot is not allowed in name any more.
MQL now has objects and structs and dot is used for referring members and methods.
I used dots in my code like you did. It was painful replacing them.
OK thanks - I wasn't 100% sure as I thought I'd compiled OK with 'dots' with new compiler before but obviously not.
Thanks a lot MetaQuotes!!

| I used that also. Don't remove/replace the dots, switch to the new structure MqlRates - MQL4 Documentation |
Array Copy Rates | New structure |
---|---|
#define ACR.Time 0 // Array Copy Rates #define ACR.Open 1 #define ACR.Low 2 #define ACR.High 3 #define ACR.Close 4 #define ACR.Volume 5 #define ACR_COUNT 6 double acr[][ACR_COUNT]; : ... ArrayCopyRates(acr, NULL, newPeriod); : Print("High at ", TimeToStr(acr[i][ACR.Time]), " was ", acr[i][ACR.High] ); | MqlRates acr[]; : ... ArrayCopyRates(acr, NULL, newPeriod); : Print("High at ", acr[i].time," was ", acr[i].high );You simplify and get type checking. |
I omitted to mention I am still trading on MT4 platform. Are your comments still valid in this case?
thanks

Is there a way to integrate help and/or some sort of context sensitive help in those editors?
Do they have MQL code highlighting or do you use c/c++?

Just use C++ code highlighting. Works for me.

I have recently tried to modify an existing MQ4 indicator and with the new (joint MQL4/MQL5) compiler have masses of errors produced from a program that has worked perfectly well when compiled with the old MQL4 compiler. Below is an example:
Errors from above code:
Has the compiler changed that much or am I doing something wrong?
thanks for any help.
