Ask for OPEN I-O statement set the open input flag in SMF 62

We need to make statistics on how files are used on our system. For that we use SMF record 62. But when the file is open in I-O in a Cobol Program, COBOL open the File In OUTPUT only, so the flag Input Processing in field SMF62MC1 remains to NO.
We would like COBOL strictly respects statements and generate the macro corresponding to an open I-O and not only open OUTPUT so Input processing flag would be set to Y and statistics would be accurate.

    This RFE is being rejected for the below mentioned reason.

    COBOL calls DFSMS macros to do physical I/O for all files. The logging of SMF records is done by DFSMS, not directly by COBOL. COBOL leverages the same behavior of the I/O macros as in other non-COBOL the programs.

    For VSAM file, when DFSMS opens a file by setting the flag bit "OUT", it can support both input and output operations. A running program may potentially contain reads. This should be taken into account would using the statistic records. The same logging could have happen from a non-COBOL program.
