Excuse me, for not getting the terms right and I will try to be clearer

I have a class MyClass, with a method called FormatPrice
that I can call from the command prompt like this

SET CLASSLIB TO Classes
oMyClass = CreateObject("myClass")
myPrice = "1234444.444444444"
?oMyClass.FormatPrice(myPrice)
1234

And the first line in my FormatPrice method is

parameters MyPrice

I have copied the code for the FormatPrice method to a prg class
definition

DEFINE CLASS 	testclass as Session olepublic	
PROCEDURE 	FormatPrice(myPrice as String) 				
Parameters MyPrice
*** rest of code
EndProc
EndDefine

then created a DLL like this

Build Project 	VFPopubtest From oPubClass.prg	
Build Mtdll 	VFPoPubTest From VFPoPubTest recompile

Then at the command prompt called this function like this

>
oVfpDll = CreateObject("VfpOpubTest.TestClass")  
myPrice = "1234444.444444444"
? alltrim(oVfpDll.FormatPrice(myPrice)  
1234

Normally, this works fine. However, suddenly, the oVfpDll.Format_Price
does not work unless I first remove the "parameters MyPrice" statement
from the Format_Price Method from MyClass. Of course if I do this, then
the Format_PRice method, when called from MyClass, no longer works.

I can't figure out why this is happening. I have tried unregistering the
VFPoPubTest DLL and deleting it. Is there something else I can delete or try?

Thanks so much
