Let's say someone accidently mis-types a macro name in their code. If the erroneous macro is not typed in a string, it will return a 0 result. However, if that same erroneous macro is included in a string, with NoMacrosInStrings=off, it returns <unknown:err.

Since some macros (ie @error) return numbers, including 0, I don't think an erroneous macro should return 0 as a result. Shouldn't they all return the "<unknown:macroname"?

Code:
 
break on
? @kix

$=setoption("nomacrosinstrings","off")
? "@err"
? @err
$=setoption("nomacrosinstrings","on")
? @err
