This User Guide describes how COBOL programs produced in a BS2000 environment can be
prepared for compilation,
compiled with the COBOL2000 compiler,
linked into executable programs and loaded into main memory, and
tested for logical errors in debugging sessions.
In addition, it includes details of how COBOL programs
utilize BS2000 facilities for information exchange,
process cataloged files,
sort and merge files,
take checkpoints and use them for subsequent restarts, and
communicate with other programs (program linkage).
In chapter "Processing XML documents" it also explains how XML documents are processed.
In chapter "COBOL2000 and POSIX" the manual also describes how the COBOL2000 compiler and the programs it generates can be used within the POSIX subsystem of BS2000/OSD and on how the POSIX file system is accessed.
Familiarity with the COBOL programming language and with simple applications of BS2000 is prerequisite to understanding this manual.
Language elements of the COBOL2000 compiler are discussed in detail in the “COBOL2000 Reference Manual” [1].
Other publications are referred to in the text by their abbreviated titles or by numbers enclosed in square brackets. The full titles are listed with their corresponding numbers under “Related publications”.

Information under BS2000/OSD
When a Readme file exists for a product version, you will find the following file on the BS2000 system:
SYSRME.<product>.<version>.<lang>
This file contains brief information on the Readme file in English or German (<lang>=E/D). You can view this information on screen using the /SHOW-FILE command or an editor. The /SHOW-INSTALLATION-PATH INSTALLATION-UNIT=<product> command shows the userID under which the product’s files are stored.
