Language doesn’t matter

My father is a land-surveyor (geodesist if you will). Nowadays he uses a notebook for his field measurements, but there was a time when he used a scientific calculator. Recently he’s notebook went dead, so he wanted to move back to his Casio scientific calculator. But, ups! Not in use for a while the battery ran out and the geodetical programs are gone. So I have to type my old programs back to the small computer. I thought I’ll share one of them as a example that programming language does not matter. What matters is how you use it and how well others could use your work. So let my share small app that I wrote back in high school for my fathers Casio fx-4500P Scientific Calculator.

A"X":B"Y":C"X":D"Y"

G=A:H=B:I=D

P=0

Lbl 1

{E}"X":{F}"Y"

E=0=>Goto 2 ∆

P=P+C*(F-B)

A=C:B=D:C=E:D=F

Goto 1

Lbl 2

P=(P+C*(H-B)+G*(I-D))/2

P:"P"▲

Voila! You can calculate a polygon field. So quit the holly "C# vs VB" war. Both are good. Very good 😉
