Hi People
I want to write some code but I got a problem with the solve() function, what I got is this:
test()
Prgm
Local a,b,c,d,e
Dialog
Request "a",a
Request "b",b
Request "c",c
DropDown "solve for", {"a","b","c"},d
EndDlog
expr(a)->a
expr(a)->b
expr(a)->c
if d=1 Then
solve(m=n*(1+p)/o|m=a and p=b and o=c,n)->e
Disp e
End If
EndPrgm
And it fails on solve( with "Argument must be a variable name"
What am I doing wrong? Help!
PD: Excuse my Engrish  |

shouldn't this be in the 68K programming section?

I don't know anything about 68k basic, but would defining n before you try to use it change anything?
EDIT: Or maybe not defining it. Try delvar n or whatever.

@alexrudd: No, it would not. The [font="courier new;font-size:9pt;line-height:100%;color:darkblue"]n tells the solver which variable to solve for.
@kyo: You did
[font="courier new;font-size:9pt;line-height:100%;color:darkblue"]expr(a)->a
expr(a)->b
expr(a)->c
which should be
[font="courier new;font-size:9pt;line-height:100%;color:darkblue"]expr(a)->a
expr(b)->b
expr(c)->c
though I don't think that would cause your problems. Do you mind if I neaten your code a bit? I'm not sure if it'd help, but it's worth a try.
[font="courier new;font-size:9pt;line-height:100%;color:darkblue"]test()
Prgm
Local a,b,c,d,e
Dialog
Request "a",a,0
Request "b",b,0
Request "c",c,0
DropDown "solve for", {"a","b","c"},d
EndDlog
If d=1 Then
Pause solve(expr(a)=n*(1+expr(b))/expr(c),n)
ClrIO
DispHome
EndIf
EndPrgm
If the [font="courier new;font-size:9pt;line-height:100%;color:darkblue"]requests don't work, just take off the "[font="courier new;font-size:9pt;line-height:100%;color:darkblue"],0" at the end. It disables alpha-lock in later versions of TI-OS (at least, I think it's later versions.) Out of curiosity, what kind of calculator do you have?

@IAmACalculator
Thanks for the input, but I got the same err message(It's driving me nuts) 
BTW I got a Voyage.
In the expr(a)->a,b,c was just a copy/paste problem :blush:
and for the ",0" It work but the voyage don't need this.
Again thanks dude for the input.  |

No problem, though I don't see what I did to help.  |
