Hi Joe,

>it just doesnt like that = .t. ...fox only see's it as a function, not a property?

From what you wrote from the help there, it is a function. You wrote :

>Function:
> boolean = TColumnOn( mux as integer, channel as integer, errr as integer )
> TColumnOn( mux as integer, channel as integer, errr as integer) = boolean

I don't know much VB but it seems to be possible to set a value by assigning a value to a function call ? This looks VERY weird to me. I don't think there is a way to do that in VFP. In any standard design (that I know at least), you'd wheter set a property directly or the property would be HIDDEN or PROTECTED and you'd set it by passing a parameter to a function call.

If it's really a function, I don't think you can get around this. However, VFP seems to see it as an array, and this would look more normal. Try to issue PEMSTATUS(DM916,"TColumnOn",3) and see what this returns. If it says Method and the only way to set the flag to .T. is to pass a value to the function call, you'll have to call the support for this component and see if there is another way. However, if it says Property than it's because you used a bad subscript to access the array. Maybe the err parameter is causing that.

Hope this helps,
