One switch to cycle effects

How would i use one switch to cycle through these effects in stead of the four switches here? ie 'Press' effect one loop, 'Press' effect 2 loop and so on.

Heres the code:

W EQU H'0000'
F EQU H'0001'

INDF EQU H'0000'

INTCON EQU H'000B'
OPTION_REG EQU H'0081'
TRISA EQU H'0085'
TRISB EQU H'0086'
CMCON EQU H'001F'

;----- STATUS Bits --------------------------------------------------------
IRP EQU H'0007'
RP1 EQU H'0006'
RP0 EQU H'0005'
NOT_TO EQU H'0004'
NOT_PD EQU H'0003'
Z EQU H'0002'
DC EQU H'0001'
C EQU H'0000'

Thanks

Just step the mode from a single switch.

how do i do that?

Have one switch on the io port and monitor it for being pressed.
Have a variable called mode and add 1 to it each time the button is pressed.
If the number gets to 4 reset it to zero.

Then in your program sequence the lights depending on the variable mode.

Dude thanks for the help but im very much a newb at asm coding, could you mabey edit my code to show me how to do that?

I have done exactly what you want in the attached file.
It does 12 different sequences but you can change it to any number at all.
