st: Extracting column information

[Michael Carney <carneymh@bc.edu>]

I have a data set of security prices over time, each price corresponding to a date column in the format, e.g., 8-Aug-1998. If I would like to take the prices for the first ten days of the month and place these prices in a separate column what commands should I use?

Thanks much,
Mike
