how to reference the last bar of a data set

["Tim McCaughey" <TimM@xxxxxxxxxx>]

I would appreciate it if anybody on the list might be able to help me with
this.

I would like to send some system performance statistics to excel using
FileAppend. At this stage I just want to send % profitable trades at the end
of a data set. That is when the system reaches the last bar of the data set,
to be able to send the % profitable figure to an excel spreadsheet.

the question is how do I reference the last bar of the data set ? Say the
last day of data is 26 July 99, is there a function that identifies the date
of a bar ?

thanks in advance.

regards

Tim.
