Hi Friends I have a dude with a delay rutine and how many cicles it take,

this is the code:

DELTX
              MOVLW         89H   ;
              MOVWF        SERDEL1 ;
DELTX2   DECFSZ       SERDEL1 ;
              GOTO           DELTX2   ;
              DECFSZ        SERDEL2 ;
              GOTO            DELTX   ;
              RETURN    ;

and : can I calculate the number of cicles that take like:

#cicles = 2 + SERDEL2*(2 + 3*SERDEL1)
