Changing member attributes
You can use the Change Physical File Member (CHGPFM) or Change Logical File Member (CHGLFM) command to change certain attributes of a physical or a logical file member. For a physical file member, you can change the following parameters: SRCTYPE (the member's source type), EXPDATE (the member's expiration date), SHARE (whether the member can be shared within a job), and TEXT (the text description of the member). For a logical file member you can change the SHARE and TEXT parameters.
You can use the Change Physical File (CHGPF) and Change Logical File (CHGLF) commands to change many other file attributes. For example, to change the maximum size allowed for each member in the file, you can use the SIZE parameter on the CHGPF command.
