Based on docs this is seems to be the case for VMS Basic as well.

If /TYPE_DEFAULT=INTEGER then 1 and 2 are integer literals
otherwise (including /TYPE_DEFAULT=EXPLICIT) they are FP literals.

Which is why I want the 2 qualifiers - one to require that
variables are declared and one to make 1 and 2 integer literals.

Alternatively I could just learn VMS Basic.
