From HP-65 Programming:

Quote:Note that the HP-65 powers up with programs entered to give default functions to the A-E keys (1/x etc.). Pressing f PRGM removes these programs.

And then later:

Quote:This program uses label A which was used in other examples. The calculator will allow you to use the same label again and this can be a useful feature but it can also lead to confusion as the calculator will always go to the next A downward in memory from the current position.

Thus I assume that you're still having the initial program or part of it in the calculator:

Code:

001: 23    : LBL
002: 11    : A
003: 35    : g
004: 04    : 1/x
005: 24    : RTN
006: 23    : LBL
007: 12    : B
008: 31    : f
009: 09    : SQRT
010: 24    : RTN
011: 23    : LBL
012: 13    : C
013: 35    : g
014: 05    : y^x
015: 24    : RTN
016: 23    : LBL
017: 14    : D
018: 35 08 : g Rv
019: 24    : RTN
020: 23    : LBL
021: 15    : E
022: 35 07 : g x<>y
023: 24    : RTN

Then I key in 40 LBL A, and then sometimes it returns 0.00, while sometimes it returns 0.03

That's what I get with:

40
1/x
0.03

Quote:However when 0.03 was returned after keying a value for LBL A, even pressing Clx, typing 50 for B will return 0.07 and C will return a weird value.

Could it rather be 7.07?
That's what I get with:

50
√x
7.07

Thus make sure to press f CLEAR PRGM in W/PRGM mode before entering Dieter's program.
