Datamax v1.1x Control and Branch, Variable against a specific pattern, Follows Pattern = B$$?4

Chapter 5 : Using Processes

5.2.2.Control and Branch

General introduction	The Control and Branch process allows you to compare the contents of
	a variable against a specific pattern.
	Depending on the result of the check, the program will branch to the
	defined destination—a screen, label or code line.
Control and Branch	To compare a character pattern with the contents of a variable, proceed
	as follows:
	1 Add the process Control & Branch to your label program
	2 In the If Value box, select the variable for which you want to
	compare the character pattern
	3 In the Follows Pattern box, select the pattern. This pattern can
	consist of:
	ƒ The Letters A to Z to specify a specific letter
	ƒ The numbers 0 to 9 to specify a specific number
	ƒ The dollar sign ($) stands for `any numeric character'
	ƒ The double quotes (") stand for `any alphabetic character'
	ƒ The underscore (_) stands for any alphanumeric character
	ƒ The interrogation mark (?) stands for `ignore'
	ƒ The asterisk (*) stands for `ignore the rest of the input from
	this point on'
	4 In the Then go to box, select the action to be performed or the
	screen to go to if the test result is true.
	5 In the Else go to box, select the action to be performed or the
	screen to go to if the test result is false
	6 Click OK
Example	The following variable contents give the following results:
	If,
	Follows Pattern = B$$"?4*
	Then,
	Variable Contents	Result
	B21C14BB34	True
	A21C14BB34	False - first character not "B"
	B999A4	False - fourth character not alphabetic

If the contents of the variable [A5] Product Description satisfy the pattern, then the application will continue. Otherwise, it will branch to Screen 2.
