Hi,
I've inherited some code that uses the stdev() function for calculating standard deviation. I cannot find any documentation on this function on Exelis' web site, nor on my installation. There is, of course, documentation for stddev(), which does the same, so I'm trying to locate where this stdev() comes from and what differences, if any, there are between these. How can one determine where a procedure/function comes from?
Thanks,
Seb

Excelent, it's been obsoleted so I'll replace with stddev().
More generally, how can one find where a procedure/function is if it's not in a file with the same name?
Thank you, David,
Seb
