COBOL is available in two different implementations: COBOL74 and COBOL85. These correspond to the ANSI-74 and ANSI-85 levels of COBOL, respectively.
Both the COBOL implementations incorporate a full range of tasking capabilities. With few exceptions, the same statements for performing tasking functions are provided in each language. In the following descriptions, statements about COBOL refer to all three COBOL implementations unless otherwise specified.
For further information about COBOL85, refer to the COBOL ANSI-85 Programming Reference Manual, Volume 1: Basic Implementation. For further information about COBOL74, refer to the COBOL ANSI-74 Programming Reference Manual, Volume 1: Basic Implementation.
