Scope and temporary index

Posted: Wed Aug 04, 2010 09:30 AM

Hello

I need to sort columns (xbrowse) for a scoped dbf

Is there a way of creating temporary index ? or should i copy the records to an array and browse the array ?

Thanks for the help

Richard,

All you have to do is supply xBrowse with an array of record numbers. For details see this thread:

From the Ng , Index command

 WHILE &lt;lCondition&gt; specifies another condition that must be met by
 each record as it is processed.  As soon as a record is encountered that
 causes the condition to fail, the INDEX command terminates.  If a WHILE
 clause is specified, the data is processed in the controlling order.
 The WHILE condition is transient (i.e., it is not stored in the file and
 not used for index updates and REINDEXing purposes).  The WHILE clause
 creates temporary orders, but these orders are not updated.
