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 Very Happy

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) Surprised
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. Smile

I'm at my wit's end then. You localized all your variables, and it works perfectly on mine. Sorry, dude.
