HXTT DBF
String functions in SQL with HXTT DBF

We're using HXTT DBF v7.0, and we've noticed a problem with using string functions in SQL statements. In particular if we use the RIGHT(), LEFT(), or SUBSTR() functions, the performance is very negatively affected, with queries taking 3 times longer or more. Is this a known issue? Is there a way to improve the timing of these queries?
