INITIALIZE

Determining the Sending Operands
The initialize operation determines the sending operand in each implicit MOVE
statement:
°
If you include replacement, the sending operand is the literal or sender
associated with the category of the receiving operand.
°
If you omit replacement, the sending operand is the implied figurative
constant SPACES or ZEROS, as this table shows:
The value of sender is established before the implicit MOVE statement
executes.
•
Execution of the Implicit MOVE Statements
For each receiving operand, the initialization operation executes an implicit MOVE
statement of the form:
MOVE SENDING-OPERAND TO RECEIVING-OPERAND
The implicit MOVE statements are executed in the order that the receiver s
associated with their receiving operands appear in the INITIALIZE statement
(reading from left to right). When a receiver references a data structure, the
affected elementary items are initialized in the order that they are defined within the
data structure. Tables within data structures are initialized element by element.
•
Operand Overlap
The storage area referenced by a sender cannot be the same as or overlap the
storage area referenced by a receiver. If this rule is violated, the operation is
undefined.
