To retrieve pages in a workfile there is the @pagelist function. Is there something similar for retrieving open workfiles? Open databases?

No.

In that case, would you consider adding it? Especially a @wflist function would be very handy when writing e.g. addins.

We'll contemplate it, although it is somewhat tricky since EViews allows untitled workfiles, multiple workfiles with the same name, and multiple instances of the same workfile.

That does indeed make things trickier. But in that case, how can my program know which of two identically named work files is active? Can I be sure what workfile will be selected by wfselect?

No. The answer, as a user, is to ensure you don't give your workfiles identical names :)

I see. Usually, I am all for giving the users free reins (making the application crash through infinite loop etc.). Here, however, I would prefer if either you gave the users some way to programmatically discern between identically named workfiles or, perhaps a lot easier, just put up a one workfile per name restriction. Allowing workfiles to be opened under an alias would also be a welcome, related feature.

(It is not that I myself would do such a perverse a thing as to name two workfiles identically, but I write e.g. addins for my users and there are no ends to what they might dream of doing. )
