Syntax:
set print set print "-" set print "<filename>" [append] set print "|<shell_command>" set print $datablock [append]
Without "4#4filename5#5", the output file is restored to 4#4STDERR5#5. The 4#4filename5#5 "-" means 4#4STDOUT5#5. The append flag causes the file to be opened in append mode. A 4#4filename5#5 starting with "3#3" is opened as a pipe to the 4#4shell_command5#5 on platforms that support piping.
The destination for print commands can also be a named data block. Data
block names start with '$', see also inline data (p. ).
