Getting a return value from a sub/function in asp

[zensunni]

Do ASP subroutines have this? How about functions? And, what's the difference between asp subroutines and functions?

Thanks for any help.

Subroutines in ASP do not return values. They exist only to perform repetitive tasks. Subroutines also cannot take an object as an argument. So if I wanted to pass a recordset object to a subroutine and have it perform a certain task on it, I wouldn't be able to.

Functions on the other hand do return a value and are use to more or less calculate things or return results. Functions, unlike subroutines, CAN take an object as an argument and therefore manipulate that object.

For instance, I wrote a simple function in order to close a recordset, because I'm lazy.

Example of a function returning a value

Function Devide(iNum1,iNum2)
   iTemp = Num1/Num2
   Devide = iTemp
End Function
 

It takes two arguments, both numbers - devides the numbers, and returns the result by setting the function name ("Devide" in this case) equal to the result, therefore returning the function

Devide(2,2) will return 1
