example python ppl with subroutines hp prime

[Liamtoh Resu]

The following demonstrate the useage of subroutines in python and ppl.
A simple pi approximation was used.

edit: fixed ppl code, was missing predeclaration for cls().

python:

Code:


#PYTHON name
# aprxpi02
import math

def pintro():
  print ("aprxpi02 pi approximation")
  return

def api():
  return 355/113

def pout():
  q1 = api()
  print ("pi = ", q1)

pintro()
pout()

#end 
 
EXPORT aprxpi02()
BEGIN
  PRINT;
  PYTHON(name);
END;

ppl

Code:


// aprxpi01
// predeclare subroutines
cls();
pintro();
api();
pout();

// main program
EXPORT aprxpi01()
BEGIN
cls();
pintro();
pout();
end;

// clear screen
cls()
begin
print();
end;

// print intro
pintro()
begin
print("aprxpi01: pi approximation");
end;

// pi approximation
api()
begin
return 355/113;
end;

// print output
local q1;
pout()
begin
q1 := api();
print("pi = " + q1);
end;

// end of source code

This is for those who are looking for a starting point.
