Here the QRG says that ?X> is a "greater than X" test, or ?0< is a "less than zero" test. However, the command name says exactly the opposite: if 0<X then X is greater than zero, not less. This would mean that for instance ?X< 01 actually tests if X > R01. ?!?

You're absolutely correct - I need to double check what's done in the code and then change the text to reconcile function name and descriptions. Thanks for keeping me straight.

I'd suggest something like FLOAT. Or maybe UNFIX. ;-)

I couldn't agree more with you - yet even the humble HP-32S call this FIX ALL so I thought I'd go with the float - I mean with the flow ;-) So the jury is still not done on this one, watch this space for the next rev.

Yes, one of those that kept poping up in my programs was Y<Z? so I decided a no-compromises approach was needed and included the 5 most-frequently used stack regs, {X, Y, Z, T, L} so you can stretch things to the point testing for L<T? if so desired.
