History

History specifications may appear in the body of dataset, table and array specifications. There is no limit to the number of history specifications which may appear in each of the allowed specification bodies.

There are two allowed formats for the history specification. The first is the single string form whose general format is given by

         history string

where

• history is the history specification keyword. This is used to begin a new history specification.
• string is the text which comprises the history. It must be a literal string.

The second form is given by

        history < free-format-text >

where

• history is the history specification keyword. This is used to begin a new history specification.

• free-format-text is the text which comprises the history (delimited by $<$ and $>$). It may be spread over several lines.

For example

    dataset "ds1" 
    < 
        history < 
            Updated by a.n.other

            and a.u.thor 
                > 
    >
