   All required modules are supported at the highest level defined by the standard. In the following list, the shorthand notation for describing module levels is shown in parentheses. For example, to summarize module information for sequential input/output, the shorthand notation is (2 SEQ 1,2). The first digit indicates the level of language elements within the module supported by IBM COBOL. Next is the 3-character abbreviation of the module name as used in the standard. Finally, the 2 digits separated by a comma indicate the minimum and maximum levels of the module. For example, (2 SEQ 1,2) means that IBM COBOL supports the sequential I-O module at level 2, while the range of levels in the module is from 1 (minimum) to 2 (maximum).
   • Nucleus (2 NUC 1,2)
     Provides internal processing of data within the four basic divisions of a program and the capability for defining and accessing tables.

   • Sequential I-O (2 SEQ 1,2)
     Provides access to records of a file in established sequence. The sequence is established as a result of writing the records to the file.

   • Relative I-O (2 REL 0,2)
     Provides access to records in either a random or sequential manner. Each record is uniquely identified by an integer specifying the record's logical position in a file.

   • Indexed I-O (2 INX 0,2)
     Provides access to records in either a random or sequential manner. Each record in an indexed file is uniquely identified by the value of a key within that record.

   • Sort-Merge (1 SRT 0,1)
     Orders one or more files of records, or combines two or more identically ordered files of records, according to a set of user-specified keys.

   • Inter-Program Communication (2 IPC 1,2)
     Allows a COBOL program to communicate with other programs through transfers of control and access to common data items.

   • Source Text Manipulation (2 STM 0,2)
     Allows the insertion of source program text as part of the compilation of the source program. COBOL libraries contain texts which are available to the compiler at compile time and which can be treated by the compiler as part of the source program.

   In addition, the following optional modules of the standard are supported:
   • Intrinsic Functions (1 ITR 0,1)
     Provides the capability to reference a data item whose value is derived automatically at the time of reference during the execution of the object program.

   • Debug (1 DEB 0,2)
     Monitors object program execution through declarative procedures, special debugging lines, and a special register, DEBUG-ITEM, which gives specific information about execution status.

   • Segmentation (2 SEG 0,2)
     Refreshes independent segments when required.

   The following optional modules of the standard are not supported:
   • Report Writer
   • Communications
   • Debug (2 DEB 0,2)
