Within an allocation specification, a SOURCE VAL statement specifies the value that the ALLOCATE command assigns to a source cell in an allocation operation after it successfully allocates the value that the cell contained before the allocation.
The default value of SOURCEVAL is NA
, which means that ALLOCATE sets the value of each of the allocated source cells to NA
following the allocation. When you specify CURRENT as the SOURCEVAL, then the allocated source cells retain the values that they had before the allocation. When you specify ZERO
as the SOURCEVAL, then ALLOCATE assigns a zero value to each source cell that is allocated.
Syntax

Parameters
Specifies that the value of a source cell after the allocation equals its value before the allocation.
Specifies that the value of a source cell after the allocation is zero.
Specifies that the value of a source cell after the allocation is NA
. (Default value.)
