Version 7.29 (12/16/00) Fixes "Error 168" bug at side prompt; Allows option for accepting
negative entries (Shift2 Shift5); Allows quantity to be double-keyed
for verification if desired; Fixes memory storage problem; changes
alpha * to ' for "feet"; Changes in handling "Next section?" and
"edit section?" prompts.
Version 7.53 (11/11/00) Ensures that calculations will be saved separately
if price and quantity are entered. This means that 123x4= 5= 123x6
will be saved as two calculations: 123x9 and 123x6. Other bug fixes
are also included.
