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? Jeff
