HP 15C Programming
I am trying to copy a programme from the programme list for HP 15C in the MoHPC.
It is a programme to solve quadratic equations.
Here is the listing:-
001 f LBL E
002 g F? 8
003 GTO .9
004 STO 3
005 Rv
006 CHS
007 STO 2
008 g x^2
009 x<>y
010 2
011 *
012 STO 1
013 RCL* 3
014 2
015 *
016 -
017 f PSE
018 g TEST 2
019 GTO .8
020 SQRT
021 STO 0
022 RCL+ 2
023 RCL: 1
024 RCL 2
025 RCL- 0
026 RCL: 1
027 g RTN
028 f LBL .8
029 g SF 8
030 SQRT
031 f Re<>Im
032 RCL: 1
033 STO .0
034 RCL 2
035 RCL: 1
036 f I
037 f Re<>Im
038 RCL 2
039 RCL: 1
040 RCL .0
041 CHS
042 f I
043 g RTN
044 f LBL .9
045 STO 3
046 f Re<>Im
047 STO .3
048 Rv
049 CHS
050 STO 2
051 f Re<>Im
052 CHS
053 STO .2
054 f Re<>Im
055 g SQRT
056 x<>y
057 2
058 *
059 STO 1
060 f Re<>Im
061 STO .1
062 f Re<>Im
063 RCL 3
064 RCL .3
065 f I
066 *
067 2
068 *
069 -
070 f PSE
071 f Re<>Im
072 f PSE
073 f Re<>Im
074 SQRT
075 STO 0
076 f Re<>Im
077 STO .0
078 RCL+ .2
079 f Re<>Im
080 RCL+ 2
081 RCL 1
082 RCL .1
083 f I
084 :
085 RCL 2
086 RCL- 0
087 RCL .2
088 RCL- .0
089 f I
090 RCL 1
091 RCL .1
092 f I
093 :
094 g RTN
I am not particularly interested in solving a problem.
My problem is that I do not know how to programme the ":" in Lines 23, 26 , 84, and 93. There does not seem to be a key or combination of keys to enter this character.
Am I missing something??

RE: HP 15C Programming
My guess is that the author typed ":" for the division sign "÷". Most people type "/" for the division sign, but since this listing contains no other divisions, try pressing [÷] wherever this listing shows a colon and let us know if that works.

It's the division key.
