BRANCH Offset, Label0 {, Label1, Label2, ...}

Function
Jump to the program Label specified by Offset which can be a Byte or Word variable. Note that the value of Offset should not be greater than the number of labels-1, otherwise the BRANCH instruction will be skipped.

• Offset  is a Byte or Word variable that specifies the index of the address label, in the list, to branch to. If the Offset exceeds the number of labels, the program will continue at the line following BRANCH. When Offset is a Word, only the LSB is used.
• Labels  specify the possible targets for the BRANCH instruction.

Explanation
The BRANCH instruction is useful when you want to do something like this:

Test_Value:
  IF value = 0 THEN Case_0                      ' value = 0: go to label "Case_0"
  IF value = 1 THEN Case_1                      ' value = 1: go to label "Case_1"
  IF value = 2 THEN Case_2                      ' value = 2: go to label "Case_2"
  IF value = 3 THEN Case_3                      ' value = 3: go to label "Case_3"
  IF value = 4 THEN Case_4                      ' value = 4: go to label "Case_4"

You can convert a long list of IF-THEN statements to BRANCH to like this:

Test_Value:
  BRANCH value, Case_0, Case_1, Case_2, Case_3, Case_4

No_Branch:
