A Compiler for Pocket Calculators

[teenix]

Hi all,

I thought I might have a go at one so I uploaded a simple basic compiler for the HP-65 - available at teenix.org.

It bound to have a bug or two as it is hard to traverse the maze of twists and turns the software could take depending on what source code is entered.

Two files are created, one that is compatible with the CCE33 HP65 emulator and a text file as shown below.

As a simple example

loop(A, 3) // Label A - loop 3 times
a=a+1 // just increment reg a
endloop
b=a+(2*c+LN(23.5)*e)/2 // fancy calculation
stop

Output...

1. 3
2. STO 8
3. LBL
4. A
5. RCL 1
6. 1
7. +
8. STO 1
9. g
10. .
11. GTO
12. A
13. RCL 1
14. 2
15. RCL 2
16. *
17. 2
18. 3
19. .
20. 5
21. f
22. 7
23. RCL 3
24. *
25. +
26. 2
27. /
28. +
29. STO 4
30. R/S

cheers
