[Beginner Q] How to use subs/functions from external file?

[sublogic]

Hi all,

New user here, thanks for providing this forum & please bear with me...

I am trying to learn how to build my own external library of functions and/or subroutines.

Here is what I have right now:

Code: (Select All)

'$Include: 'mylib.bas'



AddNumbers

Error in message window: "Statement cannot be placed between SUB/FUNCTIONs on current line"

Code: (Select All)

' mylib.bas



' Add two numbers. Or don't.

Sub AddNumbers (a, b)

  'AddNumbersResult = a + b

  'Print "Adding: "; _ToStr$(a); " + "; _ToStr$(b); " = "; _ToStr$(AddNumbersResult)

  Print "Hello world."

End Sub

What I've tried so far:

1. Adding, removing parens to/from the call to AddNumbers
   
2. Adding, removing parameters to/from the call to AddNumbers - AddNumbers(2,3)
   
3. Adding, removing "as Integer" to/from Sub/function parameters
   
4. Using variables to call the sub/function, rather than literal integers
   
5. Removing spaces between sub/function name and parens
   
6. Converting the sub to function and back again
   
7. Moving the include directive from top to bottom
   
8. Adding a declaration of the sub to the library file
   
9. Changing all function/sub logic to simply "Hello world." just in case
   
10. Browsing the wiki entries for sub, function, include, etc.
    

The changes I made have changed the error message to say different things, but I haven't once been able to run the program after guessing which changes were required.

Any help is appreciated! Version I'm using is 4.0, Manjaro Linux. I am used to programming in other languages like PHP, Perl, Raku, Object Pascal, and others, but fairly new to this kind of library-call feature in basic dialects.
