Arrays, functions.

Hi, I would like to create a function (MyPTN) that is formed by different descriptions of patterns/market behaviors. These patterns should be declared as arrays (correct me if I'm wrong) and then define the function MyPTN that retrieves these patters/market behaviors.

Code I came up with:

Code

Array: PTN[10](0),       // Indicating 11 arrays from 0 to 10 (?) 
       numberPTN[10](0);  
 
PTN[1] = Close > Close[1];  
PTN[2] = Close < Close[1];  
{list can go on} 
 
MyPTN = PTN[numberPTN]; // Function

This is just an idea since I never worked with arrays; at the moment I am getting an error indicating the ">" sign (numerical expression expected here).
The function will be used in a strategy, it should allow me to analyze the different results of the listed PTNs.
Any suggestion is appreciated.

Note sure what system you are using and not a real programmer, but thinking issue may be it's not seeing the boolean expression as a value, so something like:

Code

PTN[1] = if Close > Close[1] then 1 else 0;

I really don't know though.

By reading the EasyLanguage PDF, I think "Function Array parameter declaration" (page 109) is the solution. But again, I never used them, and trying to figure it out, any advice is welcome.

Current possible solution but still get an error:

Code

// Boolean function MyPTN  
inputs:  
	PatternNumber(numericsimple); 
 
arrays: 
	Patterns[10](false); 
 
// List of patterns  
Patterns[1] = Close > Close[1];  
Patterns[2] = Close < Close[1];  
{rest of the list}  
  
MyPTN = Patterns[PatternNumber];

The error is in the function MyPTN = Patterns[PatternNumber] "Numerical expression expected here" ("Patterns" is highlighted).
