Copy Bytes Overlap Left-Adjusted (CPYBOLA)


Op Code (Hex) Operand 1 Operand 2

10BA Receiver Source

Operand 1: Character variable scalar or numeric variable scalar.

Operand 2: Character variable scalar or numeric variable scalar.

Description  The logical string value of the source operand is copied to the logical string value of the receiver operand (no padding done). 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 shorter of the two operands. The copying begins with the two operands left-adjusted and proceeds until the shorter operand has been copied. The excess bytes in the longer operand are not included in the operation.

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 either operand is that no result is set.
