The record size limit is imposed because z/OS data management is limited to a maximum record length of 32760 bytes. This limit is imposed for two reasons.

The record size limit is imposed because z/OS data management is limited to a maximum record length of 32760 bytes. This limit is imposed for two reasons.
- z/Architecture I/O hardware is limited to a maximum physical record size of 65535 bytes. However, the arithmetic is done using z/Architecture signed half word arithmetic, which is limited to 32767 bytes.
- 32760 is a multiple of 8.
