  declare #main-output has (binary-mode | text-mode)

  declare #main-output has (binary-mode | text-mode | buffered | unbuffered)

Usually, #main-output is written to in text mode (this is the default setting). #main-output has allows you to explicitly change the mode in which data is written.

You should always use this declaration in preference to the newline declaration for performing binary input and output.

Usually, #main-output is written to in text mode (this is the default setting) and is buffered. #main-output has allows you to explicitly change the mode in which data is written. Changing both the mode and the buffering is possible, but requires two declare statements.

For example:

  declare #main-output has binary-mode
  declare #main-output has unbuffered

You should always use this declaration in preference to the newline declaration for performing binary input and output.
