Thanks; not only does that fix the problem but as it happened that reply
appeared at precisely at the right moment to help me with the custom
UnderSurface class I'm trying to implement (i.e. a class that responds to
LOOK UNDER and PUT UNDER in a way analogous to that in which a Surface
responds to PUT ON and LOOK IN, with obvious changes to the messages
displayed); would there be any call for such a class in the standard
library?
Maybe so - does anyone else have an opinion about adding this? The "hider"
classes in tads 2 certainly seemed to get a fair amount of use, and this has
at least passing similarity to those.
