HP35s Revisited Bug # 14

Code:

-(R*156.25)/(Q*X-208.333333334)

In the first run it asks for all three variables, but in the second run it only asks for X and then returns -0.99715.

So, obviously here it uses the old result -466.92696 for both variables, R and Q:
-0.99715 = -(-466.92696*X)/(-466.92696*X-R)

Hmm would it be related to opening parenthesis?

Edit: obviously yes!
I took my former EQN and added parenthesis at the beginning

Code:

-R*156.25/(X*1.77951304201-208.333333334) => 31.32309
became 
-(R*156.25)/(X*1.77951304201-208.333333334) => -70.20286

Now R is also totally skipped, meaning that the second time XEQ EQN doesn't prompt for any value and returns -70.20286.

So it looks like any "(RCL X" is replaced by the former EQN result.
