DIFFERENCE BETWEEN BINDING LANG AND BIND DIR WHEN USING IN SERVICE PGM...when using binding direct..

Answer / syam

Binder Language : Set of commands (STRPGMEXP, EXPORT, and
ENDPGMEXP) to define the signature for a service program.
These commands (source type BND) are not executable.

Binding Directory : An object that contains a list of names
of modules and service programs that the binder may need
when creating an ILE program or service program. A binding
directory is not a repository of the modules and service
programs; instead, it allows the binder to refer to them by
name and type.

Binding : The process of creating a callable program by
packaging ILE modules and resolving symbols passed between
those modules.

Answer / sumit gupta

Binding Language concept is involved in Service program.
This is used when we export procedures and attach when we
create service program or when update service program.
Binding language contains certain keywords like STRPGMEXP,
ENDPGMEXP, EXPORT
STRPGMEXP is used when signature is hardcoded or *current
or *previous is specified on PGMLVL.
ENDPGMEXP is used to end the STRPGMEXP
EXPORT is used to export the symbolic name of module
(procedure)

Binding directory is used to to attach many modules and
service program.

It depends whether service program is neccessary or not, if
your binding directory contains all the procedures which
are also present in service program then no need to using
service program.
