TISERV UOW Descriptions

Individual fields in the response UOW header contain the following additional
information:
UOW-RETN-CODE
is the return code.
If no errors occurred, the TRANSFER delivery system sets this field to 0.
If an error occurred, the TRANSFER delivery system sets this field to a
positive value ranging from 4000 through 5999; these values indicate the
UOW was not processed.
If a warning was indicated, the TRANSFER delivery system sets this field to a
negative value ranging from -5999 through -4000; these values indicate the
UOW was successfully processed.
Note In the RETN-CODE field for each UOW, entries that begin with E denote errors returned to your process
by TISERV. Entries that begin with W denote warnings. All possible entries are listed for each UOW.
See Section 3 for descriptions of these errors.
RETN-CODE-DETAIL
is a code that primarily identifies an error detected by a subsystem other than the
TRANSFER delivery system, such as the GUARDIAN 90 operating system or the
EXPAND network software, and for which the TRANSFER delivery system
provides no standard handling. See Section 3 for descriptions of these errors.
Note All request and response UOWs must be aligned on word boundaries.
Software Provided
with the TRANSFER
Delivery System
The TRANSFER delivery system provides three source code files that contain
commonly used TRANSFER elements. The files are called GCOB, GLNK, and GDDL
The structure and field definitions in GDDL appear in this manual. Typical
TRANSFER elements are the interprocess communication (IPC) header that initiates a
request and the unit-of-work (UOW) definitions that describe operations to be
performed.
GCOB contains source code for Working-Storage Section definitions used in
programs written in SCREEN COBOL and COBOL.
GLNK contains the same code as the GCOB file, but without the VALUE clauses
that specify the initial values for fields. The GLNK file is used for Linkage Section
definitions.
Note GCOB and GLNK have information in addition to that produced by DDL when generating SCREEN
COBOL and COBOL. The primary additions are prefixes for all field names and many level 88
declarations for fields, as described later in this section.
