Found problem.

If incorrect string date is in large data set, it will hang up routine
without error message.


Thank you.

I have had difficulty in using the DateList function.

I am to convert string  dates "mm/dd/yyyy"  to  a date list

I have large data sets of approx. 400,000.

Using the following routine, Mathematica hangs and does not produce any


Corrected Routine;





Abort does not work. I need to do a hard Mathematica close.


The problem seems to occur when the dataset is between 200,000 and 300,000.

The routine has worked with data sets of less than 200,000.


Any idea as to what causes the problem?


Microsoft 7 (64bit), 18Gigs memory, Intel Xeon

Mathematica 8.04


Thank You,
