Than our conversation ends here.

Not because of the language, but as you are going into the realm of the
"what if's".  I have no interest in second-guessing what a language designer
might decide *his* language should evolve in.

So, you take that statement outof its context and time and are trying to put
it on several BASIC variants that have evolved sinds than, meaning for the
last 40 years ?

BASIC *might* have been bad in those days, but so is *any* programming
language in the hands of a nitwit.  I've seen enough junk over the years, in
all sorts of languages (PHP, Java, .NET, C{something}, BASIC, you name it).

So ?   They *stated* it was a bug, but I doubt it.   And even if it was
introduced by accident, what does that matter if the result is quite
usefull, and does not break anything else (read: is consistent with the rest
of the language) ?

You know what *I* find odd ?   That an "end if" may be followed by a colon
and than more code.  That certainly breaks the "multi-line if" approach. :-)

Ofcorse, *not* allowing that would be an exception to the rule that *any*
command may be followed by a colon ...

Too bad you have taken a stance, bluntly disregarding this, quite important
difference between two types of implementation of a language, where VBScript
is in the group of "do not have it", and has, to solve it, created the "end
if".

The *only* squabble we have here is if it should be allowed in a single-line
"if" or not.  Nothing more, nothing less.
