Hello!!!



    I have two things that is bothering me about data types and 

functions in asp.   Please help me clarify this things



1.) Is there a way in ASP to declare the data types of variables?

     e.g.

          In VB6

                Dim Num1, Num2 as integer

                Dim String1 as string

     Why is it that I've noticed that variables in ASP are declared only 

as Dim Num1?  What is the explanation for these?



2.)  I've made this function that will add two numbers

     

     function  add(no1,no2)

          add =3D no1 + no2   

     end function 

.

.

.

.   

    dim test

   

      test =3D add(1,4)



    Everything works fine IF the function is within the asp file BUT 

when I try to put the function on another ASP and include it and error 

occurs

    "type mismatch test".  Is there anything that I need to do inorder 

for the function to work?



Please advise.



Thanks,



Enzo :)

The reason for no type in asp as far as I know is because asp variables are

treated as variants.

 

As for your adding function try to change this line 

add = no1 + no2

to this and see if it works

add = cint(no1) + cint(no2)

 

Hope that helps ya

First. ASP is relativly new as a Programming Technology. 

All variables are Variants until you put something in 

the variable. Once that is complete, the variable takes 

on the datatype the data is. 



Second. ASP does not understand Functions on other 

pages. It sends, and compiles only the pages it asked to 

send and compile. If your function is on page1.asp and 

you are calling it on page2.asp, IIS will have no idea 

where to find your function, unless you set a pointer to 

page1.asp. The way to do that is with the INCLUDE 

statement, much like C. <!-- Include 

File="/include/page1.asp" --> add that line (Check for 

syntax) at the top of your page, and your function will 

work.



HTH,

Mike
