Converting From Binder to nld and
noft
The nld and noft utilities replace the Binder product to support the object files
created by the native C, C++, COBOL, and pTAL compilers. nld and noft are used in
the same part of the development process as Binder. You can perform most, but not
all, tasks previously performed by Binder with nld and noft.
nld and noft have different syntax and semantics than Binder. Unlike Binder, nld is
not an interactive tool. It executes a command based on what you specify on the
command line or in a command file.

Object File Differences
Because of file format differences between a TNS or accelerated object file and a
native object file, nld and noft do not operate on TNS or accelerated object files.
Unlike TNS and accelerated object files, which can be both linkfiles and loadfiles,
native object files are either linkfiles or loadfiles, but not both. For more information on
native object files, see Native Object Files on page 1-2 and Section 8, Native Object
File Structure.
