In addition to pervasive macros READ and WRITE, a macro WRITEF for the purpose of formatted output could be added.

This macro could either take a fixed number of parameters:

[@WRITEF( file, num, fieldLen );  (* always three parameters *)

WRITEF( file, num, fieldLen );  (* always four parameters *)@]

Alternatively, the macro could be variadic:

[@WRITEF( file, num, fieldlen );@] expands to ''@@`TypeOf(num)@@''[@.WriteF( file, num, fieldlen );@]

[@WRITEF( file, num, fieldlen, places );@] expands to ''@@`TypeOf(num)@@''[@.WriteFixed( file, num, fieldlen, places );@]

Unlike C's variadic printf and fprintf macros, the variadic WRITEF variant would remain type safe.
