GW> "From the programmer's point of view, writing a driver for ANSI
 GW>  output is slightly more difficult than for other kinds of terminals
 GW>  because ANSI expresses all numeric parameters as ASCII digits instead
 GW>  of binary numbers. But if ANSI output is not particularly difficult,
 GW>  writing code for an ANSI input driver is a Herculean labor. Because
 GW>  the identifying code (the "Final") occurs last or next to last (if an
 GW>  Intermediate is present), there is no way to ascertain at the
 GW>  beginning of a control sequence how long it will be. Remember, there
 GW>  may be a variable number of ASCII numeric parameters and/or selective
 GW>  parameters. If necessary parameters are missing from the control
 GW>  string, defaults must be supplied. All input from the CSI through the
 GW>  Final (or Final-Intermediate combination) must therefor be buffered,
 GW>  then parsed into functions and parameters."

Hence AVATAR ...
