I have run into this problem many times whenever I start use more then a few IF blocks in my code. The program below uses 3 IF blocks to set some variables and fade an LED using the values set by the previous IF blocks. When I try to compile this, however, I get the following error: test.src(148) line 148, error 2, pass 1: Redefinition of symbol <__ELSE_0>

When I double click on the error to see exactly what line of code it is that is causing the problem, the SX assembly code pops up. I won't post the entire assembly code since it is long. But here is the code that pertains to the IF blocks:

Start:                           ;Start:


  JNB rc.0,@__ELSE_1             ;	if rc.0 = 1 then 'catch ON command from button press and do not reset until fade complete

  SETB rc0Bool                   ;		rc0Bool = 1

__ELSE_1:                        ;	endif
__ENDIF_1:                      


  CJNE rc0Val,#255,@__ELSE_0     ;	if rc0Val = 255 then 'reset to default values when the fade completes

  MOV rc0Val,#1                  ;		rc0Val = 1

  CLRB rc0Bool                   ;		rc0Bool = 0

__ELSE_0:                        ;	endif
__ENDIF_2:                      


  JNB rc0Bool,@__ELSE_0          ;	if rc0Bool = 1 then

  ADD rc0Val,#1                  ;		rc0Val = rc0Val	+ 1

  MOV FSR,#__TRISB               ;		PULSOUT RB.0, rc0Val, 5	' delay 1 millisecond
  MODE $0F                      
  CLRB IND.0                    
  MOV !RB,IND                   
  BANK $00                      
  MOV __PARAM1,rc0Val           
  CLR __PARAM2                  
  XOR RB,#%00000001             
  MOV __PARAM4,#37              
  DJNZ __PARAM4,@$              
  JMP @$+2                      
  SUB __PARAM1,#1               
  SUBB __PARAM2,/C              
  MOV W,__PARAM1                
  OR W,__PARAM2                 
  JNZ @$-13                     
  XOR RB,#%00000001             

__ELSE_0:                        ;	endif  !!!!!!!THIS IS THE LINE THAT IS CAUSING THE PROBLEM!!!!!!!!
__ENDIF_3:                      


I don't really know how to intrepret the assembly code [ that's why I use the SXB :) ] but I know enough to realize that if I replace the zero on the ELSE line to __ELSE_3 and also replace the zero in the JNB declaration to JNB rc0Bool,@__ELSE_3 it makes everything work fine. So my question is, why is the SXB compiler using the same definition multiple times and how do I get it to stop. When I make these manual changes, the program will compile and run perfectly. But the next time I compile, it overwrites my changes and I have to manually change it back again. This is only a piece of my overall program and making all of these changes to the jillion IF blocks in the final program get really time consuming after a while.
