RGEA
Structure:
1This output will always be a hexadecimal representation which must be con verted to binary format. In this example, the conversion gives
00000000000010110010000011111111 in binary format, see Appendix H, Page 242 for a complete conversion list. Reading from right to left
you can look to see what each bit represents in Table D-5, following.

Example (carriage returns have been added between observations for clarity):
