BranchL

Syntax

BranchL Index, [Label1 {,...Labeln }]

Overview

Cause the program to jump to different locations based on a variable index.

Parameters

Index is a constant, variable, or expression, that specifies the address to branch to. Label1,...Labeln are valid labels that specify where to branch to. A maximum of 65536 labels may be placed between the square brackets.

Example

  Device = 24FJ64GA002
                                     ' Select the device to compile for
  Declare Xtal = 32
  Dim Index as Byte
  CLKDIV = 0
                                     ' CPU peripheral clock ratio set to 1:1
  Write_OSCCONH(%00010000)
                                     ' Enable PLL
Start:
  Index = 2
                                     ' Assign Index a value of 2
' Jump to label 2 (Label_2) because Index = 2
  BranchL Index,[Label_0, Label_1, Label_2]
Label_0:
  Index = 2
                                     ' Index now equals 2
  GoTo Start
Label_1:
  Index = 0
                                     ' Index now equals 0
  GoTo Start
Label_2:
  Index = 1
                                     ' Index now equals 1
  GoTo Start
'
' Config fuses for internal oscillator with PLL
'
  Config Config1 = JTAGEN_OFF, GCP_OFF, GWRP_OFF, BKBUG_OFF, COE_OFF,_
                   ICS_PGx1, FWDTEN_OFF, WINDIS_OFF, FWPSA_PR128, WDTPOST_PS256
  Config Config2 = IOL1WAY_OFF, COE_OFF, IESO_OFF, FNOSC_FRCPLL,_
                   FCKSM_CSDCMD, OSCIOFNC_ON, POSCMOD_NONE

The above example we first assign the index variable a value of 2, then we define our labels. Since the first position is considered 0 and the variable index equals 2 the BranchL command will cause the program to jump to the third label in the brackets [Label_2].
