How to store any element of variable in FOR loop in the HP 50g graphing calculator

HP Recommended
HP 50g graphing calculator

Hello HP Community

I'm writing to you because I  expect to  give me an answer for these for me the hardest task for now.

I want to write more matrix than one in FOR loop but I also want to store every single matrix described in FOR loop with the different name , as the global variable , of course . So I don't know how to do this .

Problem is that , when I hit the following code (underneath) I get just one stored matrix of n numbered matrices  .

So, my screen  prints just last matrix entered in graphing calculator HP 50g .


Please help me anyone with this problem because I'm little getting mad , cause I don't know how to solve it , and I also don't know is it possible to solve it , any suggestions or solution will be great


This is following code :


(NOTE : this sign ---> represents an arrow to right direction )


{{ "a:" "" 0 }
 { "b:" "" 0 }
{ 1 2} { } 
DROP  ---> a b
<< a b
FOR i { << #A2012h LIBEVAL>>}

In my opinion your program is more complex than needed for illustrating the problem.

I would suggest a simpler program:


<<  3 7 FOR i
    [0]  EDITB

 This program puts 5 matrixes on the stack, but does not store them into variables.

I think the easiest way to store them into memory is to store them into a list.

This can be easily done by adding:

5    →LIST


The matrixes are now in the list, and we store the list as L1 by

'L1'   STO.


So now our program becomes:


<<  3 7 FOR i
    [0]  EDITB
    5 →LIST
    'L1' STO

 When we next want the third matrix back we just have to write:

L1  3  GET

try a sequence among the lines of:

obj_to_store "var_name" count_variable + OBJ-> STO

the + will concactenate the counter varaible (1, 2, 3...) with the text "var_name". The OBJ-> will transform the string into a variable name that you can use for sto.


you migth (not sure) have to do "'var_name" count_variable + "'" +, but I am not sure.
