Dan Flatin asks if there is a way to scan for hidden variables.

If all you want to do is see if there are any, you can use Rick
Grevelle's HACKIT library to determine this easily:

Put the name of the directory on the stack, then use this:

DUP  EVAL  RCLDR  ->DIR  UPDIR  SWAP  RCL  ==

If this yields 1, then there are no hidden variables;
if this yields 0, then there ARE hidden variables.

Once that's done, you can easily find out what they are by entering the
directory, doing a VARS (that'll give the visible vars), then unhiding
everything, and doing a VARS again, and taking the SUB of this list which
shows just the newly obtained vars (they'd be the previously hidden
ones).

I hope that makes sense.   -- Joe Horn --
