Does anyone know of a way to define the length of an array with an extern variable? Please tell me this is possible somehow. Or do you not have to give a length?

I found this on the web. And I have read it cover to cover and can find no copyright, so I assume it is ok to post.

Just use the search function in Acrobat for array

I don't know why, but when you set the size of an array to int, it doesn't accept it, but when you resize the array with int, it does accept it.
ArrayResize also accept double as a size (will just delete anything after the comma).
try this,


PHP Code
extern int range = 5;
 
 
 
double s[];
ArrayResize(s,range);
