If you use SFS files in a COBOL for AIX application, compile the application using the cob2 command. The cob2_r4 command, which was recommended for compiling COBOL for AIX Version 2 applications that used the SFS file system, is not supported.
If you use shell scripts to compile COBOL for AIX applications, update them accordingly.
