Best regards from V. Re: 15C program question - John Nelson - 06-06-2007 Thanks... that's odd... normally you will see / for division. Thanks again for the heads up. Re: 15C program question - Donald - 06-06-2007 is it RCL 1 i.e. RCL 11 ? Re: 15C program question - John Nelson - 06-06-2007 No... it is a colon. Re: 15C program question - Egan Ford - 06-06-2007 If you are referring to http://www.hpmuseum.org/software/15cquad.htm then it should be RCL/, not RCL:. Register 1 contains 2a, so RCL/ 1 is required to get the correct answer. Re: 15C program question - John Nelson - 06-06-2007 Well, I treated the colon as a divide, so it really wouldn't matter. Is there something else the colon can stand for as I have seen it before, but then a few lines below I would see them use the forward slash so it was as if they were using it interchangeably, which does not make any sense.

As Valentin and others have stated, I think it's supposed to be "divide". The original intent was probably to superimpose ":" on "-", to make a divide sign. A capital theta can similarly be formed by superimposing "-" on a "0". -- KS
