Syntax

  using output as modified-sink (& modified-sink)*
     action

Argument definitions

modified-sink

stream-name indexer? (with open-modifiers)? or attachment (with open-modifiers)?

The using output as prefix creates a new output scope and attaches to it the given modified sink expressions. If a sink expression is a stream, it must be open. If a modified sink expression is an attachment, it will be opened for the duration of the output scope.

The following attachments are permitted for using output as:

1. referent string-expression, which attaches the output scope to a referent whose name is given by a string expression.
2. filestring-expression, which attaches the output scope to a file whose name is given by a string expression.
3. an external output function call, which attaches the output scope to a "connection" to an external output function. When data is written to the stream, it is processed by the external output function. This extends the ways in which OmniMark interacts with the external environment simply by adding external function libraries.

When the modified sink expression is a stream, the following modifiers are permitted with using output as:

1. a string expression containing the element content format modifiers
2. the binary open modifier

Meanwhile, if the modified sink expression is an attachment, any modifier allowed by the open action can be used.

Any output generated by action will be redirected to the output scope created by using output as.

The following variations are permitted:

• The keyword AND can be used in place of "&".
• The list of modified sink expressions can be placed in parentheses to improve readability.
