Operand 2: Character variable scalar or numeric variable scalar.
Operand 3: Character scalar or numeric scalar.
Description: The logical string value of the source operand is copied to the logical string value of the receiver operand.
The operands can be either character or numeric. Any numeric operands are interpreted as logical character strings.
The length of the operation is equal to the length of the receiver operand. If the source operand is shorter than the receiver operand, the source operand is copied to the leftmost bytes of the receiver operand and each excess byte of the receiver operand is assigned the single byte value in the pad operand. If the pad operand is more than 1 byte in length, only its leftmost byte is used. If the source operand is longer than the receiver operand, the leftmost bytes of the source operand (equal in length to the receiver operand) are copied to the receiver operand.
Predictable results occur even if two operands overlap because the source operand is, in effect, first copied to an intermediate result.
Substring operand references that allow for a null substring reference (a length value of zero) may be specified for operands 1 and 2. The effect of specifying a null substring reference for the source is that the bytes of the receiver are each set with the single byte value of the pad operand. The effect of specifying a null substring reference for the receiver is that no result is set.
