Sub won't accept parentheses around arguments

Can anyone explain this for me?
>
A sub procedure can be called with or without parentheses around the
arguments. By personal convention, I normally use parentheses. I am in
the middle of a fairly large project (for me), happily using parentheses
everywhere -- until this happened:
>
The following sub is defined in a class module.
>
Public Sub DeleteXXRecord(lngEORekNombro As Long, lngXXRekNombro As Long)
[..code..]
End Sub
>
In another (form) module, I call the sub thus:
>
Dim A As Long
Dim B As Long
>
A = [some long number]
B = [some long number]
>
DeleteXXRecord(A, B)
>
While typing this last line, Intellisense seems to be quite happy with
what
I am typing. But as soon as I newline after entering the line, it turns
red. Doing a compile gives me "Syntax error" on this line.

I have been agonizing over what could be wrong with such a simple sub
call,
trying to cut down the code to the bare basics -- all to no avail. Until
in desperation I decided to try deleting the parentheses -- thus:
>
DeleteXXRecord A, B
>
Lo and behold, this actually compiled error-free. The only sub call in
the
whole project without parentheses!

I know that many people don't use use parentheses with sub calls. I do it
mainly for consistency with function calls (I've gotten into the habit).
As far as I know, parentheses around a sub's arguments should always work.

Have I got this wrong somehow???

Thanks for any help,

In other words you can invoke a sub in two different ways
>
Call DeleteXXRecord(A, B)

or
>
DeleteXXRecord A, B

but you can't mix and match i.e.
>
DeleteXXRecord(A, B) or Call DeleteXXRecord A, B
