Greatings! I have stated a new project working with PWM and fading LEDs. All is going well until I tried to combine two simple test routines. The first two routines work fine. When I tried to use port indexing with PWM it failed. Can anyone point out my error or does the PWM command have limitations on pin discriptions? Manual says it can be a variable or pin discription, e.g. PortB.0 Is there another way to do this?

PIC16f886, PBP 2.6, using LAB X2 board.
;Cycle through PortB to fade ON then fade OFF eight LEDs in sequence.

Code:
Symbol Port_Pin=PortB  
    Avar    var byte  
    Duty    var byte            
    Cycle   var byte

;more stuff in here 
   
;--[ LED fade ON and fade OFF   ]---------  works fine!
FadeTest:     
    cycle=4    ;cycle is number of cycles of pulse    
    for Duty=0 to 100 step 1
        pwm led1,Duty,cycle
        next Duty
     cycle=1    ;cycle is number of cycles of pulse
     for Duty=100 to 0 step -2
        pwm led1,Duty,cycle
        next Duty
        low led1     ;end of routine
    pause 1000
    goto FadeTest

;--[  PortB indexing LEDs       ]--------------  works fine!

    for Avar=0 to 7

       pause 250
    next
    goto IndexTest

Comments please, Thanks.
