Process Operations

Types of Operation

Four major types of instructions can be coded on process parameters, as follows:

Arithmetic operations add, subtract, multiply, or divide field or literal values by means of simple or compound operations.
Conditional operations compare the contents of one field or literal value with the contents of another field or literal value. When the test condition is true, the specified action occurs.
Assignment operations move a field or literal value to a work field or an internal CA Culprit field.
Control operations control the flow of processing in the extract and output phases.

Each type of process operation is discussed separately below. The following table identifies CA Culprit keywords associated with process operations and summarizes their function.

Process Operation	Keyword Command	Action
Arithmetic	ADD	Adds
	MINUS	Subtracts
	TIMES	Multiplies
	DIVIDE	Divides
	COMPUTE	Performs a compound arithmetic operation
Conditional	IF	Performs a compound test operation
	EOF	Tests for an end-of-file condition
	B	Performs an unconditional branch
Assignment	MOVE	Transfers a value to another field
	CONVERT	Converts an alphanumeric value to a numeric value
Control	PERFORM	Performs an unconditional branch
	RETURN	Returns to point of branch specified on a PERFORM statement
	CALL	Calls an external procedure module
	PICK	Selects edit lines for extracting or printing
	UNPICK	Deselects edit lines for extracting or printing
	TAKE	Prints selected edit lines; processing for the report ceases
	RELS	Prints selected edit lines; processing for the report continues
	DROP	Does not print selected edit lines; processing for the report ceases
