Defining which sockets to test z/OS Communications Server: IP Sockets Application Programming Interface Guide and Reference SC27-3660-00 |

The SELECT call monitors for read operations, write operations,
and exception operations:
Each socket descriptor is represented by a bit in a bit string. The length of this bit-mask array is dependent on the value of the MAXSOC parameter and must be a multiple of 4 bytes. See Selecting requests in a concurrent server program for more information. Note: To simplify string processing in COBOL, you can
use the program EZACIC06 to convert each bit in the string to a character.
For more information, see EZACIC06.
