Non-programmer question!
An associate of mine used Excel to develop an analysis program that to date
works very well. However this program also takes Excel to its limits, so new
annual data cannot be added without taking Excel down.

He only knows as much programming (using Excel) as was needed to get the
analysis program to work. Now that he's max'd out Excel what are his options
should he decide to re-write (or contract to re-write) this program?

Thanks,
