You don't seem to remember much more than 10 or 15 years ago. Just wanted to know if that was to be expected, or your simply retarded. Ever hear of Fortran?

Now that we both agree we could care less about each other, maybe you'll stop posting rants at me.

No, that's valid syntax and the parameter will be changed. You would need extra parens to prevent the value from changing as in lngPassed = DoThing((lngValue)) > Call will prevent getting the value of lngPassed but will have the > same effect as previously. > > Call DoThing( lngValue ) parenthesis are needed.

That's the effect but it's more correct that VB evaluates the expression, passes the result ByRef, then discards the returned value: temp=(lngValue) Call DoThing(temp) "temp" gets updated but since there's no way to reference the temp value that VB created when evaluating the expression any change is effectively lost. It's the same as Call DoThing(lngValue+1) or any other expression that must be evaluated before the result is passed. Where it gets confusing for people new to VB is when CALL is omitted: DoThing (lngValue) is the same as Call DoThing((lngValue)) and not at all the same as Call DoThing(lngValue)

Sure I have, but since those languages are not VB, they are not related to my response. No one is asking about the use of Call in those languages. I'm talking about when Call originated in the VB language. That is what this topic is about. Not ForTran or ASM. -Scott

That should've been "you're" of course, as in "you are simply retarded" - HTH! -- ..NET: It's About Trust! http://vfred.mvps.org |
