In that design, how does the `printf' builtin know that the argument string is generated by a specific variable with the numeric flag? The `printf' builtin is a (builtin) command that receives arguments as strings. The arguments do not carry the contexts of how the strings are generated, (though some of the exceptions are the array assignments of the assignment builtins). -- Koichi
