Vladimir,

One way to accomplish this is to set the COLUMNS environment variable
to a large number.  You might also try calling the terminal-width
procedure with the number of columns you want.  The terminal-width
procedure is in the (system repl debug) module.  Note that there is a
different terminal width in each thread of your program, so maybe
setting the COLUMNS environment variable would be easier.

But I haven't tried these methods, so I don't know what will happen,
exactly.

Good luck,

Mike Gran
