Compiler Options

sname Option

sname name defines the section name as name, where name can be up to seven characters in length. sname has system-dependent aspects, as described below. The compiler assigns the section name as follows:

The section name is the name that you specify with the sname option.
In the absence of a specific compile-time sname option, the section name is the name of the first external function in the module, truncated to seven characters.
If no name is provided through the sname option and there is no external function in the module, the section name is the name of the first external variable in the function.
If no name is provided through the sname option, if no external function is in the module, and if no external variable is in the module (that is, the module contains only static data or functions), then the section name is @ISOL@.

sname under TSO or OS/390 Batch

The specification is

sname (name)

where name defines the section name.

The debugger uses the section name in order to locate the member in DBGLIB that contains debugging information for that section. DBGLIB is discussed in Running the Debugger under TSO, and Running the Debugger under OS/390 Batch, along with the instructions for running the compiler under each operating environment.

sname under CMS

The specification is

sname name

CMS uses the source filename as the debugger filename, but the section name is distinct and independent of the source filename. The sname option enables you to use a nondefault SECTION-NAME argument in debugger commands.
