Building blocks, which are definitions that appear at the beginning of a definition 
file and are referenced by TYPE clauses that appear later in the file. Building 
blocks are present in ZPWYDDL, but are not generated for ZPWYC, ZPWYTAL, 
ZPWYCOB, or ZPWYTACL.
Location
The files are located on the disk volume chosen by your site. The default disk volume 
used by the Install program or the Distributed Systems Management/Software 
Configuration Manager (DSM/SCM) utility is $SYSTEM.
Which Files Do You Need?
An application that sends DSM commands to and receives responses from the 
Pathway subsystem needs the following definition files in the appropriate programming 
language:
SPI (ZSPI) definition file
PWY (ZPWY) definition file
An application that retrieves event messages issued by the Pathway subsystem needs 
the following definition files:
SPI (ZSPI) definition file
PWY (ZPWY) definition file
EMS (ZEMS) definition file
For example, a management application written in COBOL that sends commands to 
and retrieves event messages issued by the Pathway subsystem would copy or load 
the following definition files:
ZSPIDEF.ZSPICOB
ZSPIDEF.ZPWYCOB
ZSPIDEF.ZEMSCOB
If your application manages subsystems other than Pathway, it also needs the 
definition files required by those subsystems. For instance, you might want your 
Pathway management application to manage an associated TMF subsystem as well. If
