Can you give more detail of the program and what problem you're having. Different programs will work different ways. Is this in a module, or did you copy the program from somewhere? (It doesn't sound like you wrote it yourself.)

HI GARTH THX FOR HELPING OUT. IF YOU GOOGLE TRIANGLE PROGRAM FOR HP 41CV IT WILL COME UP, IT GOES FROM 001-142. PLEASE GO TAKE A LOOK AT PROGAM LISTING IT STARTS OUT AT 001 LBL "ABC" ETC.... PLEASE SEE IF YOU THINK EVERYTHING LOOKS IT CAN B INPUT PROPERLY ON THE 41 CV, SEE IF THERE IS ANY TRICK INPUTS LIKE LINE 013. ALPHA X SHIFT COS SHIFT TAN Y, WHEWWW, LOL . TO CONCLUDE..... AFTER I INPUT WHOLE PROGRAM AND END BY PUTTING GOTO .. FOR END, THEN I TRY TO EXECUTE PROGRAM IT SAYS NONEXISTENT.... OR ANOTHER TIME I ENDED IT, PROGRAM WENT TO 002.....?????? THX

Oh, I thought you meant data input. Now I think you mean program input. Well, I found quite a few HP-41 triangle programs, but apparently not the one you're talking about. What do specific trouble lines (like line 13) have in them? One I imagine you might be seeing, after a GETKEY, is GTO IND X. To enter that, press SHIFT GTO 2nd . X . BTW, the END line gets put in automatically. You don't have to put it in yourself.

Hello,

From your description it seems that this is the program you're referring to: Triangle Solutions for the HP-41.

Well, line 013 is the "x exchange y" instruction, it's directly available on the keyboard just above the shift key. No need to use XEQ here.

On line 002 GTO IND T should be entered with Shift GTO Shift . T

Lines 69 and 121 X<> Z should be entered with XEQ Alpha X Shift COS SHIFT TAN Alpha which will display X<> __ , then enter . Z

Do you have any other instruction that is difficult to enter?

Thank you I will try that.there is a couple of more I have questions about......Lines: 006,007,014,016,038,089109,111....I am pretty sure lines 016,038 and 111 is just using alpha button. Just want to b sure thx in advance. P.s. at end I input shift goto.. Right.

Line 006 R^ : XEQ Alpha R Shift Enter Alpha
Line 007 ST* Z : STO x . Z
Line 014 ST+ X : STO + . X
Line 016 ACOS : Shift COS
Line 038 ASIN : Shift SIN
Line 089 ST* 02 : STO x 02
Line 109 ST+ X : STO + . X
Line 111 SQRT : it's the square root key, directly on the keyboard.

Yes, entering 1 CHS gives -1. To have two separated instructions you can do: 1 ENTER then delete ENTER and press CHS.
