Syntax error

[j4e8a16n]

Ti complains about that:

Local res,temp,str,nheader,temp2,head,dhead,svar,usage

string(usage) = "- le nom de la fonction à dériver (souvent f ou g)- la variable de la fonction à dériver (souvent x ou t)- l'expression de la fonction à dériver"

If string(ex) = "0" Then Disp [usage] Endif

Thanks for your attention

Hi,

 

I am not 100% sure what the intent of the code is but I re-wrote it a little and it displays the “usage” string wen the “ex” variable is 0 and doesn’t display anything otherwise.

 

 

Local res,temp,str,nheader,temp2,head,dhead,svar,usage

Request "Ex? ",ex

usage:="- le nom de la fonction à dériver (souvent f ou g)- la variable de la fonction à dériver (souvent x ou t)- l'expression de la fonction à dériver"

If string(ex)="0" Then

  Disp usage

EndIf

 

 

The “Request” command is to test the code. I imagine it wouldn’t be needed in your main program.

 

Is this helpful?

 

Regards,

- Harshal
