Importing data

GAMS
1

Hi,

I’ve been working with GAMS for just a couple of weeks and I would
like to ask for some help.
I have to import data from a .txt file to a .gms file. The data in
the .txt file has not a specific format and I do not need to import
all data from the .txt file. Are there any functions to readout
specific cells from the .txt file?

Thanks a lot!

No. But GAMS comes with some utilities for manipulating text files.
Some of the more popular tools are sed and awk. The web offers a few
tutorials for these utilities. Moreoever, there is an excellent book
http://oreilly.com/catalog/9781565922259/ about sed & awk. Take a look
at model awkqap, awktsp, and seders in the GAMS model library.

Hope this helps.
