Input and output

COBOL for Linux® on x86 supports input and output for sequential, relative, and indexed files with the Db2®, MONGO, SdU, SFS, and STL file systems, and also supports input and output for sequential files with the QSAM file system and RSD file system.

Line-sequential input and output is supported by the native byte stream file support of the operating system.

Sizes and values of the returned file status information can vary depending on which file system is used.

COBOL for Linux on x86 does not provide direct support for tape drives or diskette drives.
