MFJAMS supports the following parameters. They are supported as documented in the IBM documentation unless otherwise stated below:
| Column Heading | Description | 
|---|---|
| DSN | Dataset Name - e.g. 
                              					 xxxxxxxx - MFIDSA.DO.NOT.DELETE.B1057624.KSDS1 where 
                              					 xxxxxxxx is one of: 
 | 
| C | Cataloged: Y=yes, N=uncataloged, S=Spool | 
| C | CHARSET: EBCDIC or ASCII | 
| DSOR | Dataset Organisation | 
| RecF | Record Format | 
| Lrecl | Logical Record Length | 
| Blksi | Block Size | 
| KyL | Key Length | 
| KyOff | Key Offset | 
| GDG/SHR | Maximum GDG generations or VSAM SHAREOPTIONS value. If the first entry returned by LISTCAT is a VSAM dataset, then the column heading is SHR to show the share options; otherwise, the heading is GDG to show the bias limit. | 
| S | Roll-up disposition: S=SCRATCH, N=NOSCRATCH | 
| E | GDG EMPTY (E) or NOEMPTY (N) | 
| UK | UNIQUEKEY (UK) / NONUNIQUEKEY (NU) for AIX and PATHs | 
| RU | REUSE (RE) / NOREUSE (NR) | 
| XD | Extended dataset type (P=PDS, L=PDSE, I=PIPE, H=HFS) | 
| XR | Extended RBA support (Y=yes) | 
| XT | Extended Type: A=Aix, C=Cluster, P=Path, M=Model, E=Aix Index, J=Aix Data, I=Index, D=Data, ?=Unknown | 
| Dataclas | The MGMTCLAS is shown on line #1 and DATACLAS on line #2 | 
| Volume | <null> | 
| RecMn | Minimum Logical Record Length | 
| RecMx | Maximum Logical Record Length | 
| Changed Job/On/At | Jobname/date/time of the process that last updated the dataset's catalog record | 
| Created Job/On/At | Jobname/date/time when created | 
If the ALL option is specified, a new line entitled PC FILE lists the physical file.
Comments:
ENTRIES and LEVEL are mutually exclusive; you can specify only one of them. LEVEL(*) is the default if neither is specified.
