Syntax:
set print set print "-" set print "<filename>" set print "<filename>" append set print "|<shell_command>"
Without "5#5filename6#6", the output file is restored to 5#5STDERR6#6. The 5#5filename6#6
"-" means 5#5STDOUT6#6. The append flag causes the file to be opened in append
mode. A 5#5filename6#6 starting with "4#4" is opened as a pipe to the
5#5shell_command6#6 on platforms that support piping.
