Hello!

I have a small question concerning to the procedure call.
I have the following procedure:

private sub procedure_name (ByVal name1 as string)
...
end sub

When I call it I just write:
...
procedure_name("something")
....

When I add some extra parameters into the procedure that is:

private sub procedure_name (ByVal name1 as string, ByVal name2 as boolean)
...
end sub

then the procedure call would look like this:

call procedure_name("something",True)

Why???? Why there are some cases when word "call" is needed (because
excluding it, it will give us an error) and why it is not needed in the
other cases?

When do we have to use word "call" to call procedure or function?

Thank you for posts
