Control Data Corporation 3300 Reference Manual page 3

PREFACE
The features of USASI COBOL/MASTER specified in ihis manual conform to the United States of
America Standards Institute (USASI) COBOL Standard. The USASI specifications define a Nucleus
for internal processing and eight functional processing modules: Table Handling, Sequential Access,
Random Access, Random Processing, Sort, Report Writer, Segmentation, and Library. The
Nucleus is divided into two levels, low and high.
USASI COBOL/MASTER is implemented at the high level of the Nucleus. Of the modules, only
Random Processing and Segmentation are not implemented. All other modules are implemented
at the high level. The Report Writer module can be omitted from the COBOL library. USASI
COBOL/MASTER runs under control of the :MASTER operating system.
Additional features of COBOL are implemented in USASI COBOL/MASTER to facilitate operating and
to support system interfaces. The inclusion of COBOL features over and above the USASI standard
is not prohibited by the standard; however, an installation option is available to diagnose all non-
USASI features as errors at compile time.
The Business Data Processing Unit (3312) must be present to compile and execute USASI COBOL/
MASTER programs on a CONTROL DATA® 3300 computer. The CONTROL DATA® 3500 computer
comes equipped with the Business Data Processing hardware.
This manual is organized in the traditional manner of Identification, Environment, Data, and Pro-
cedure Divisions with the exception of the Report Writer and Library modules which are described
in separate chapters.
