  1. PFORD Bhagyashree Bohra Deepti Jindal Shringika Porwal

  2. Outline • Introduction • Overview • Examples • Implementation details • Lessons learned

  3. PFORD • A programming language for making programming easier and translates complex languages • Some Generation: C++ Java

  4. Goals • Portability - interpreted and executed by a java interpreter. • Ease of use - very simple and quick to start

  5. What can the language do? • Basic operations – addition, multiplication, power, modulus… • Advanced operations – complex string operations , array operations • Translation

  6. Operations and Relations

  7. Statements

  8. Functions and Function call

  9. Internal functions (include string) • Join • Join(a,b) joins strings a and b. • To Lower • toLower(m) makes all the characters in a string lower case • To Upper • toUpper( m) makes all the characters in a string upper case • Mean • mean() computes the mean of an array • Stddev • stddev() computes the stddev of an array • Sum • sum() sums all the elements of an array • PrintArray • print() prints all the elements of an array • Sort • sort() sorts all the elements of an array

  10. Example 1: 8 11 startprogram w = 3; x = 10; func incw() { w=w+1; return w; }; func incx() { x=x+1; return x ; } ; func myfoo(y, z) { output y+y; x = 1; output z; } ; myfoo(incw(), incx());

  11. What does translation entail • Multiple Walkers. (total 3 right now) • One for stand alone • On each for each language • C++ • Java

  12. Code Statistics (partial, currently in CVS)

  13. Lessons Learned • Fully investigate the feasibility of the supporting tools • Ie. translation • Get advice from experienced people • When an easier method of implementing classes of function exists, use it • power • When in doubt see Mx

  14. Future • Additional functionality • Translation to more languages • ie perl, C#
