How is the compiler suppose to know that the programmer may have
meant
program ifelif
if (.TRUE.) i = 42
if (.FALSE.) then
j = 42
end if
end program
As for the message that you think makes no sense, I suspect
the parse has identified (.TRUE.) as a malformed expression.

As far as I know, there are two possible statements starting with if:
if (<expr>) then
if (<expr>) <statement>
The compiler should recognize that *something* is missing, be it either a then
or a statement.

Well, the message objectively makes no sense because there is no assignment
whatsoever. At the very least, the message is confusing.
