 Posted: December 1, 2010 8:03 PM Post subject: Indirection Problems |
 |
|
| Code: |
:For i,1,n,1
:Local #("cx"&string(i)),#("ca"&string(i))<--"Error: Invalid variable name in a Local statement"
:Input "blahblahblah",#("cx"&string(i))<--"Error: Indirection string is not a valid variable name"
:Input "blahblahblah",#("ca"&string(i))<--"Error: Indirection string is not a valid variable name"
:EndFor
|
I can't figure out what is wrong with the indirection statements. I have all variables involved assigned as local variables (i,n). Any clarification on what is wrong with the given strings would be greatly appreciated. I really want this vector program to be done and working; everything else on the program works except this lone For...EndFor block. If you need to see the rest of the program, just let me know. |

| Nevermind, I have created a new code segment that will serve as an alternative for this one. |

I know you found another solution, but just for reference: I wonder if perhaps the parenthesis you used were unnecessary? I haven't tried it on my TI-89, but maybe you could try simply:
| Code: | For i,1,n,1
Local #"cx"&string(i)
EndFor |
or, failing that, perhaps
| Code: | Local stringi
For i,1,n,1
"cx"&string(i)->stringi
Local #stringi
EndFor |
Not sure if the first method would allow declaring multiple local variables using a comma, but I suspect it would.
There is some more information on http://tibasicdev.wikidot.com :
Local
Indirection
Hopefully this helps. |

Hi ghost ROM,
I just might add, that it might be easier to run your program in a separate folder, and forget about trying to define local variables. Allow the variables to be global, and if they are in a separate folder that you don't use regularly, then it should be ok if they get overwritten.
I was able to get this code to run fine:
Input "blahblahblah",#("cx"&string(i))
Verify that the value of i is what you expected it to be.
Hope this helps!
Regards,
