Foreword

The Standard and ISO /IEC 1989.2002 "Information technology - Programming language COBOL" of non-equivalent. This standard replaces GB/T 4092-1992. This standard and GB/T 4092-1992 the differences are as follows. --- The standard configuration of the 4092-1992 GB/T made a major adjustment. GB/T 4092-1992 is divided into 12 parts, the present Standard to integrate them into a standard; --- Achieve increased compliance requirements; --- Part of the term to do a larger adjustment. Which increases the term 116, revised the terms 39, delete the term 242; --- Adds object-oriented programming features; --- Enhanced additional features for anomaly detection and reporting; --- Enhanced algorithm portability; --- Increased local character data type for processing multi-bit coded character set; --- Increased primitive binary and floating-point data types; --- Increasing user-defined functions; --- Adds file sharing and record locking; --- Increasing the internal functions; --- Enhanced interoperability with other languages. The standard proposed by the People's Republic of China Ministry of Information Industry. This standard by the National Information Technology Standardization Technical Committee. This standard was drafted. China Electronics Standardization Institute. The main drafters of this standard. Fuqing Hua, Peng Jing, Li Haibo, Xie Qian, Zhang new exhibition. This standard was first published in 1983, in 1992 made the first amendment to the Second Amendment. information Technology Programming language COBOL

1 Scope

This standard specifies the COBOL syntax and semantics. This standard specifies. --- Written form COBOL compile groups; --- Compile a compiler group performance; --- Run effect execution unit; --- Compliance requirements to achieve to meet the language elements of its definition; --- Meaning of language elements that are not explicitly defined; --- Dependent processor performance language elements. The standard does not specify. --- COBOL compiler set in writing, the manner in which the processor compile them into executable code; --- Methods, modules connect or bind to a statement on the time of activation function or program is running, when appropriate procedures or methods in the series When the translation when unknown binding except in the case the inevitable happened; When --- parameterized class is expanded; --- Define a local environment on the processor and make it available mechanisms; --- Error message, tag information or form or content of the warning message; The form and the content list generated --- compile time (if any); --- Implementors proposed form of documents conforming to this standard product; Sharing resources between --- run unit, except for the file.
