If you are using binary data files you should use the BINARYDATA RCP before you name the data files.
Binary data is held in records resembling a punch card image; a punch card contains 80 columns each with 12 codes; each code may be punched or not punched. There are up to 960 separate bits of data in a card image (80 columns of 12 punches each). There are many ways of storing card image records on disk; CL handles most of the generally recognised formats.
IMPORTANT: CL can handle binary data records of any length using READ and PUNCH commands. To read 80 column records you must use a field of 80 columns with these commands.
If you receive "column binary" data from another company it will probably be a .CSI file. CL users are recommended to use .CBA files. Another major software supplier uses .CBE files.
