Hi newsgroup

My boss gave me the following assignment. Please make an interface between
GAMS and EXCEL. This interface should have a lot of functionality and be
able to visualise data.

What is the easiest way to accomplish this? I thought of using EXCEL and VB
to make an application that had the feel of being a standalone program and
use components/objects from EXCEL.

My question to you is: What book should i buy for reference/introduction ?
;-)

Thank's in advance
Mark
