Syntax

  string-part _ string-part


Purpose

The _ character is used to concatenate two or more string parts into a single string. Note that the maximum length of an OmniMark string is 2,048 characters, excluding the surrounding quotation marks and any underscores used to enter long strings.

The _ character must be used when joining quoted SGML or XML names. It is also useful when a string exceeds a single line in length.

Unlike the underscore keyword, the || keyword is a run-time concatenator allowing returned values, rather than only strings, to be joined. This makes the || keyword more flexible than the underscore, so the underscore should be used only in the cases noted above.
