I think you are right. This is perhaps the better
thing to do.
I just sketched what changes to the compiler
would be needed to *allow* (and correctly handle)
access to imported string constants.
And now that I have done THAT (it’s not difficult, but
it requires some shenanigan with item conversions in
ORG.loadStringAdr, ORG.StrToChar, ORG.CopyString,
etc. to use the SB base of the exporting module if
needed, and also setting org.lev also for constants),
I agree with you that one should just issue an error
message when an external string is accessed -
which of course is a trivial change to the compiler.
Or not even allow string constants to be exported
in the first place. This would effectively turn them
into aliases for string literals visible only in the
module where they are declared.
One of those things that one *could* debate
endlessly, but where a debate is not really
worth our time..
