Well RawDoFmt() works pretty well like sprint(), except there is one additional
parameter. sprintf(outstring,format,values...) puts the output starting at
memory location "outstring".

Well, RawDoFmt(format,values,routine,outstring) has the additional parameter
"routine" which points to a function that copies the characters to "outstring"
one by one.

Therfore "routine" may either copy the characters to outstring, or perhaps
it may choose to ignore that parameter and output all characters to the
serial or parallel ports.

Look at page A-36 of the blue-green Amiga ROM Kernel Reference Manual, Includes
% Autodocs. It shows you how sprintf() is implemented using RawDoFmt().
