Syntax

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

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

Usually, #main-input is read from in text mode (this is the default setting for non-UNIX systems) and is buffered. #main-input 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-input has binary-mode
  declare #main-input has unbuffered

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