Here are some examples in PPL [/code]...

Code:


// 2023.0901 pretty-prime v0.3b
#pragma mode(separator(.,;) integer(h32))

//=============
EXPORT prog()                               // most literally

  PRINT("Sin Θ = OPP/HYP");
  INPUT(a,"Sin Θ");
  INPUT(b,"OPP");
  INPUT(c,"HYP");
  IF a=0 THEN 
    d:=b/c;
    e:=ASIN(d);
    PRINT("B/C = "+d);
    PRINT("Θ ="+e);
  END;
END;

//=============
