Gaussian integration for the HP-11C/15C

[Marcio]

Hello,

Does anyone know how to port this program originally coded for the 11C by Valentin Albillo to the 15C?

Code:


    01 LBL A     17 LBL 0     32 RCL 1     
    02 STO 1     18 RCL 1     33 GSB E    
    03  -        19 RCL 3     34  8       
    04 RCL I     20  +        35  *
    05  /        21 GSB E     36 STO-2
    06 STO 0     22  5        37 RCL 0
    07  2        23  *        38 STO+1
    08  /        24 STO-2     39 DSE
    09 STO+1     25 RCL 1     40 GTO 0 
    10  .6       26 RCL 3     41 RCL 2 
    12 SQRT      27  -        42  *
    13  *        28 GSB E     43 18
    14 STO 3     29  5        45  /
    15 CLX       30  *        46 RTN
    16 STO 2     31 STO-2     47 LBL E

I can not figure out why it won't work on the 15c. I thought it was because DSE (step 39) requires a pointer (I) on the 15C. Well, it is not.

Thank you.
