[Help-glpk] Reading Column Headers from CSV files

[Jeffrey Kantor]

Hi --

I'm attempting to write a portfolio optimization model in GMPL, and would like to read return

data from a .cvs file.  The file would include a variable number of columns with the column

header containing a short string for the stock ticker symbol.

I'm having trouble figuring out how to read a variable number of columns in GMPL, then use the

column headers as entries in a set. Is it possible to do this?
