Dynamically adding FILESYSTYPE statements in BPXPRMxx

When you dynamically add the FILESYSTYPE, NETWORK, and SUBFILESYSTYPE statements, you can make the change permanent without having to reIPL by using the SETOMVS RESET command. If you want to change the values, you will have to edit the BPXPMRxx member that is used for IPLs. You can also dynamically add the parmlib statements currently supported by SETOMVS, such as MAXPROCSYS.

To display information about the current FILESYSTYPE, NETWORK, or SUBFILESYSTYPE statements, issue the following command: 
DISPLAY OMVS,PFS
