Hello Roman,

I don't think I'm following you.  I already have a '?'
inserted after the literal.

Again here is one version of the code:

: 0? ? drop if 0 ; then 1 ;

I would test this as

1 0?

or 

0 0?

So the ? is immediately following the literal 0 or
1.  Also half of the time this works.  If it was 
wrong all of the time I could understand it.
I'm quite puzzled by this.

Please test it.  It's only one line of code but
it's driving me bonkers.

Regards,

John M. Drake
