The Cause of Error 800A139B
The underlying cause is a syntax error, in the sense that you are missing a closing bracket. With this error pay close attention to what comes next after:
In this example the script is looking for a closing bracket ‘]’, and not an opening bracket. This was the example:
Stephen Gentry kindly sent in both the problem and this solution. From what I gather, Stephen is trying to execute sophisticated pattern matching code:
Correct syntax "<\[\w+\]>" and "\<\[\w+\]>"
While I have not studied the escape character in this sequence, it seems to me that a backslash acts as an escape character. thus \<[ does not escape the [ (it escapes the <.
In this example: "<\[\w+\]>"
Both the opening and closing bracket are escaped by the backslash \[ and later \]. This is why the solution works, and why the problem complains about an expected closing bracket.
