I think Blue is better than Red. Bagels beat donuts hands down! (unless you're *not* in NYC; then damn near ANYTHING beats a bagel!) Chicago Pizza beats New York Pizza. 42 Connery over all others (Moore, Brosnan, Lazenby, Dalton, Craig) Anything with butter. As to *your* question... What sorts of things does the customer expect to *do* with those scripts? And, (besides space) what other constraints are you needing to place on those actions? E.g., any timeliness constraints? Performance? Numerical precision? etc. Who is the intended user: *just* the client? Or, will these things be exposed to users? What sorts of things do the scripts interact with (displays, etc.)? E.g., do you need to be able to manipulate a GUI without constraint? Or, are you just serving up text and/or canned dialogs? What sort of user input device (keyboard, keypad, etc.)? Other I/O's? I opted for a (bastardized) Limbo as my scripting language. But, I use it to generate "real" applications and not just automate some preexisting actions. However, it won't fit your memory requirements. Can you tolerate something as "crude" as a bastardized BASIC? I.e., add "product specific" hooks to it to address some of the special needs (displays, etc.) at a "native" level. A BASIC interpreter/compiler can be really small. The same can be said of C interpreters, mini-compilers (JIT). But, you'd be targeting a different class of "developer" (user). --don
