set stream? stream-name indexer? open-modifiers? to string-expression

The set (or set stream) action applied to a stream is used to associate a buffer with the named stream and to initialize the contents of the buffer.

Any of the open modifiers permitted for open may be specified in the set (or set stream) action.

Prior to OmniMark V3, set buffer was used instead of set or set stream. OmniMark still supports set buffer but its use is deprecated.
