CoCoS stands for Common Coding Standards, or alternatively Common Cobol Standards or Cobol Coding Standards.
It is pronounced as [kókòz] and spelled charlie-oscar-charlie-oscar-sierra.

With CoCoS the opportunity opens to develop Cobol Systems and Programs in a universal way with common agreement and understanding when reading Cobol Sources.

CoCoS is not a framework, but might be seen as such. The suggested Standards do, however, interfere with program flow and support good practice.

The ruleset does not contain syntactic sugar, though the association with the name calls for it: you need hard labor to crack it and the internals will reward you.
