Top2n:

I apologise for the inconvenience.

But the file creates, not with the requested data,

result - one column filled with 17 rows of boolean true

There's a stringStringSetChar - swore at the beginning,

I changed it toboolStringSetCharacter - this might be the reason for the boolean error.

string PrepareString(string s)
  {
   bool exit = false;
   int index = 0;
   string str = s;
//----
   while(!exit)
     {
       index = StringFind(str, ".", index);
       if(index > -1)
           str = StringSetChar(str, index, ',');
       else
           exit = true;
     }
   return(str);
  }

While I won't be at computer, I will not be able to give any hints. I will be in 4 hours, it's my day off.

Actually voidOnStart(), althoughint is allowed

[Mikhail Toptunov]

Artyom Trishkin:

No, it's not the string -StringSetChar

Vitalie Postolache:
Actually you needvoidOnStart(), although it's allowedint

Thanks, but not the point!

[Vitalie Postolache]

Top2n:

No, it's not about the string -StringSetChar

Thanks, but not the point!

Are you sure you candeclare an array like this?

double arrayZ[ARRAY_SIZE_X,ARRAY_SIZE_Y];

[Mikhail Toptunov]

Vitalie Postolache:

Are you sure you candeclare an array like this?

double arrayZ[ARRAY_SIZE_X,ARRAY_SIZE_Y];

And yet it didn't swear. Fixed it, no change.

Doesn't it also fail on this one?

int handle =FileOpen(fileName,FILE_CSV|FILE_WRITE,' '), x, y;

[Mikhail Toptunov]

Vitalie Postolache:

Doesn't it also fail on this one?

int handle =FileOpen(fileName,FILE_CSV|FILE_WRITE,' '), x, y;

I don't understand why X,Y and I don't see the catch anymore

[Vitalie Postolache]

Top2n:
I don't understand why X,Y and I don't see the catch anymore.

It's your code, I certainly don't understand why you have it written that way.

[Mikhail Toptunov]

Vitalie Postolache:
That's your code, I certainly don't understand why you have it written that way.

It's just a variable declaration
