| Op Code (Hex) | Operand 1 | Operand 2 | Operand 3 | |
|---|---|---|---|---|
| 03D7 | Attribute receiver | Exception description | Materialization option |
Operand 1: Space pointer.
Operand 2: Exception description.
Operand 3: Character(1) scalar.
The instruction materializes the attributes (operand 3) of an exception description (operand 2) into the receiver specified by operand 1.
The template identified by operand 1 must be a 16-byte aligned area in the space if the materialization option is hex 00.
Operand 2 identifies the exception description to be materialized.
The value of operand 3 specifies the materialization
option. If the materialization
option is hex 00, the format of the exception
description materialization is as follows:

If the materialization option is hex 02, the format
of the materialization is as follows:

The first 4 bytes of the materialization identify the total number of bytes provided for use by the instruction. This value is supplied as input to the instruction and is not modified by the instruction. A value of less than 8 causes the materialization length invalid (hex 3803) exception to be signaled.
The second 4 bytes of the materialization identify the total number of bytes available to be materialized. The instruction materializes as many bytes as can be contained in the area specified as the receiver. If the byte area identified by the receiver is greater than that required to contain the information requested, then the excess bytes are unchanged. No exceptions (other than the materialization length invalid (hex 3803) exception) are signaled in the event that the receiver operand contains insufficient area for the materialization.
