BRANCH
Syntax
branch index, [label1, label2, label3, ..., labelN]
• Index - is a variable, constant or expression that is used to reference a label in a list. The index
is 0 based.
• Label - is a list of constant labels that are jump points in a program.
Description
The BRANCH command will jump to a label dened within the brackets. The label used for the
jump is determined by the pointer index. The only limits to the number of labels within the
brackets is the available program memory.
Example
Connect to the following program with the terminal window at 9600 baud. Enter a value from 0
to 4. The program will jump to the label specied by the value typed in. The BRANCH command
is a great way to build a long conditional jump list based on some value range. User interactive
menu systems are one possibility.
