Chapter 5 : Using Processes

5.2.1.Case and Branch

General introduction	The Case & Branch process allows you to compare the value of a
	variable input with up to six other variables or values.
	The Case and Branch command will check for equality only.
	As soon as an equality is found, the process branches to the defined
	destination (Label, or screen ...)
	If all the comparisons are false, the action or screen in the Otherwise
	Goto list is performed.
Case and Branch	To compare a variable or value with other variables or values, proceed
	as follows:
	1	Add the process Case & Branch to your label program
	2	In the Case Value box, enter the value or select the variable you
	3	want to compare.
		In the Equal boxes, enter the values or select the variables you
		want to compare against the value or variable selected in the Case
	4	Value box.
		In the corresponding Goto boxes, select the action to be
	5	performed or the screen to go to if the test results are true.
		In the Otherwise Goto box, select the action to be performed or
	6	the screen to go to if the test results are false.
		Click OK
Example	In this example, the user is prompted to enter a product type. The Case
	and Branch process then compares the entered product type with
	predefined values. These values can be constants or variables. This
	example shows both. The contents of [A8] Product Type are compared
	against the value found in variable [A9] Product Option and against the
	constant HARDWARE.

When a match is found, the label program branches to a screen according to the product type entered. If there is no match, the program goes to screen 2. If the product type entered matches the contents of [A9] Product Option, the program goes to screen 3. If the product type entered is HARDWARE, the program goes to screen 4. The program flow and process statement are shown below.
