Now I know I'm getting old. The following code produces the following error when I compile it:

Error: 'myInt' - integer number expected.

Code:
Inserted Code
xtern int myInt=21;
int init()
  {return(0);}
int deinit()
  {return(0);}
int start()
  {
   double myArray[myInt];
   return(0);
  }

MT got you going??

The error is not in the 'extern int myInt=21;' veriable, its in the use of it in defining the array elements in this statement 'double myArray[myInt];' you cannot define the elements in an array with a veriable it has to be a number or a #define constanst. You can resize the array there after with a veriable but when you first define it, it must be a number or you can leave it as just 'double myArray[];' and resize it later, the problem is when first defineing it, with a variable the compiler will not be able to set the memory allowcation right, hay its MT.

Yep. It's my old age, MT and the fact that I'm blonde (but hey, the blonde helps hide the gray hairs!).

I understand what you're saying. I re-did the code and re-compiled w/ no errors.

New code: (Thanks BTW).
Inserted Code
xtern int myInt=21;
int init()
  {return(0);}
int deinit()
  {return(0);}
int start()
  {
   double myArray[];
   ArrayResize(myArray, myInt);
   return(0);
  }
