"say I need a program that when I fill in the dimensions of a parallelogram (i.e its height and length) I get its area, volume and perimeter and then sum of the perimeter and the area. Input h: and l: Output P: A: V: and P+A"
Excuse me but I couldn't resist, my mathematical guts just gave a jump upon reading your 'example'. I know that you intend it as just an example, not an actual need, but certainly it was as bad an example as it gets, namely:
- Giving just height (h) and length (l), there's no way you can compute its volume (V), you need an additional parameter for that, namely the width (w)
- Computing "sum of the perimeter and the area (P+A)" is absolutely nonsensical, their dimensionality is different and there's no way they can be added up meaningfully. It's like asking for the sum of volts and pounds ! :-)
That said, good luck with your 48/49 programming. For the HP-71B you'd simply use something like this:
10 INPUT H,L
50 PRINT P,A,V,P+A
