Please explain why its illogical.  All I see is a method to terminate a
"then" before an line-end is encountered.  It would definitily solve
Mayayana's initial problem:

x = x + 9: If x > 10 Then x = 10 *end if*: If x < 0 Then x = 0

That a line-end *can* be used to terminate a single-line "if" does not mean
it should be the *only* way to do it.  :-)

Nope.   Its just how quite a few (but definitly not all!) languages have
defined it.   It does not mean its the *only way* anyone may implement it in
his language.

I know of languages which use your above description and work as Mayayana
described (continuing after a "then" if no "else" is found, or after the
first command after the "else").

Ofcourse, several of those languages have "command grouping" commands and/or
symbols, making it again possible to have a "then" or "else" execute an
abitrary number of commands/equations.  Just think of how C++ does it, using
"{" and "}" to group commands together.

VBS (and a number of other languages) do not have such command-grouping
symbols/commands/methods, so they needed to think of something else.
