Why is this Variable

[Mackeral]

I have this code

Row_Id = "0a"
Call Parse_Line(Prog, 0, Line, Orig_Code, Calling, Row_Id)

which calls this function with a line of code in it:

Function Parse_Line(Prog, Lvl, Code, Orig_Code, Calling, Row_Id) As Boolean

        Flag = Parse_Expression(Prog, Lvl, Code, Orig_Code, Calling, Row_Id)

and the definition of Parce_Expression is

Function Parse_Expression(Prog, Lvl, Code, Orig_Code, Calling, Row_Id) As Boolean

When I run this code, I get a compiling error in "Parse_Line" that says "Row_Id" is "ByRef argument Type Mismatch" (no error number given).

There is no definition of "Row_Id" in the program definition, and the code worked an hour ago. I have explictly gone through and put "as String" on all definitions references to "Row_id" and I still get the error.

Any idea what might be going on? This kind of stuff drives me batty when something works and then stops.

I think it has to do with your passing Row_Id ByRef (the default when nothing is specified) which means you are giving your code access to the memory location used by VB to store values in that variable. I am guessing that one of your assignments to it in the called function uses Row_Id in a different way (underlying data type) than was used in the original calling program. I presume you are not attempting to physically change the original value in the first calling program, so I would declare that variable this way in each function header...

ByVal Row_Id As ****

(change the **** to a real data type) after which I would think your code should work fine.

Solved: Why is this Variable Giving an Error

Stupid Programming Error

Thanks for your responses. I'd spent a couple of hours on this before posting and really thought I'd come across a system error.

The problem was calling the wrong subroutine with a different number of attributes.
