Arguments: stream
This function returns the column number where the next character
will be written, or nil if that is not
meaningful for stream. The first column on a line
is numbered 0. This function is used in the implementation of the
pretty printer and the format
~T directive. For every character output stream class that is defined,
a method must be defined for this function, although it is permissible
for it to always return nil.
See also streams.htm for general information on streams in Allegro CL.
The documentation is described in introduction.htm and the index is in index.htm.
