COBOL for AIX Version 4.1.1 or later programs will ignore the FILEMODE option and create large-format files.
In COBOL for AIX, Version 3 and Version 4.1, you could indicate that a COBOL for AIX program should create small or large-format files by specifying a runtime option FILEMODE(SMALL) or FILEMODE(LARGE) respectively. Beginning with version 4.1.1 of COBOL for AIX, you can no longer indicate that a COBOL for AIX program should create small or large-format files. However, you can read or write files created in small-format.
For compatibility with COBOL for AIX Version 2, Version 3 and Version 4.1, see File format for details.
