Both models are driven by a specific list of input arrays (most are numeric matrices). The function qkInputArrays lists them. That function together with qkInputArchive can deliver a list of all the Case Studies which use any input array, and we will soon have a table menu allowing us to click on any. Here's an example using pdf files , but pdf is too slow and that list only includes a few Case Studies (all ProCash). There's a better menu example which I'll post here when remember where it is. We can also write a function to sweep thru all uses of an input array to determine the types of properties our Excel facility needs to be prepared to handle.
