RB port sequencer

Hi, All:
Finally, I came to idea to use PIC in my applications.
Small, cheap and easy to make application than by using
digital IC.
Bought PICBasic compiler and got problems:
-not debugging options
-not able to use assembler
-limited number of operators.
So I wrote my the first program for PIC16F84A
and appreciate any help to correct my program.
I want to buy in nearest future PICBadic Pro and now my focus is
to learn what kind of applications could be supported by PICBasic
compiler.
Best Regards,
Leonid
Here is the first program:
Because of limited numbers of operators in PICBasic I used Pulsout to hold output pins configuration during W7 -time.
Full sequence inRight rotattion is B1,B2,B3,B4,B5,B6
and during Left rotation is B7,B8,B9,B10,B11,B12.
B1-B12 numbers could be any depends of application.
Pin RB6 connected to LED indicates status of PIC Run/Stop
Pin RB7 does not used.
