Simple program

[Flippy]

Hi all,
Many years ago, I bought a new HP 32s RPN calculator (yes, I'm old).
Long story short, one of my co-workers dropped it in a tank of water and it sat over the weekend.
So, I tossed it and moved on with a cheap TI-30 but could not get used to it (no RPN).
so, I bought a slightly used 35s.
my problem is I can't get it to work like I'm used to my 32s.
Here is the simple program...

PRGM TOP
M001 LBL M
M002 INPUT I
M003 25.4
M004 ×
M005 STO M
M006 R↓
M007 FIX 3
M008 INPUT M
M009 25.4
M010 ÷
M011 STO I
M012 FIX 5
M013 R↓
M014 GTO M001

the problem I'm having is when its waiting for input, I should be able to add, subtract,
or do anything I want before making the conversion (R/S). I know this is an easy fix but
still, I'm at a loss.

could someone please give me the answer?
Thanks

It works for me. Are you running in RPN mode? For example.
XEQ M ENTER
(displays "I?")
1 ENTER 2 / R/S
(displays M? and 12.700)
ENTER 12 - R/S
(displays I? and 0.02756)

Thanks for that response David.

I'm still missing something..
I should be able to go between Inch and Metric without using the enter button.

I? display
1 R/S
M? display 25.4
10 -
M? display -9.8 ~~should be M? display 15.4

At least that's how it was on my 32s for 25 plus years.
I constantly change back and forth from Imperial blueprints to Metric WEDM displays.
The work around is to hit enter before making any calculations but that's not how it was.

Please advise.[/color]

On the 35s, the INPUT command disables stack-lift. See page B-5 of the 35s user's manual. The 32s manual says it works the same. Are you sure the program works for you on a 32s?

You could get around the problem by adding ENTER before each INPUT command. That would put the value in the Y register also. In essence, you'd be pre-lifting the stack.

Hope this helps,
Dave
