I was doing PT tech consulting (relative of mine) and they used a 16-bit Foxpro application (accounting + inventory) for far longer than they should have. (Upgrade would have been 5 figures, and it was working great, so why change?) As it turns out, the software shipped with a DOS ui as well, that supported 100% of the functions + features that the GUI Windows version supported. .... which made it easy to run under SSH/Linux/Dosemu, which was used a few times when a bug in the original Foxpro runtime prevented printing on any version of Windows based on the NT4 kernel ....
