I am trying to figure out why Ti BASIC is the worst language ever. Every other language, if you want to use a user defined function within a user defined program, you simply write the function above (or below) the sub routine and then you can call it to your hearts delight...why is Ti BASIC failing me here? (I am using Ti89 Titanium.) All I want to do is a simple test here. Here is a user defined function that simply take an argument and then returns that argument (and this works if I type it directly into my calculator) Code (Text): Func newdisp(stuff) Return Stuff EndFunc Now I want to do a simple test program that calls newdisp and uses it Code (Text): () Prgm newdisp(100) EndPrgm So it should just display '100' on the home screen. I would think that the structure of the program would be something like Code (Text): Func newdisp(stuff) Return Stuff EndFunc () Prgm newdisp(100) EndPrgm or maybe Code (Text): () Prgm newdisp(100) EndPrgm Func newdisp(stuff) Return Stuff EndFunc But if this worked I would not be here......the above to codes I am writing in Ti GraphLink and then sending to my calculator. Any thoughts?
