You can use the following table to determine the decimal
or hexadecimal value associated with the GETSOCKOPT/SETSOCKOPT OPTNAMES
supported by the APIs discussed in this document.
The command names are shown with underscores for the assembler language.
The underscores should be changed to dashes if using the COBOL programming
language.
Languages that cannot easily handle binary values, such
as COBOL, should use the decimal value associated with the command
where necessary.
The hexadecimal value can be used in Macro, Assembler and
PL/I programs.
