Distributed editing

If you have made a connection to the workstation, you can also specify a workstation file name such as C: \AUTOEXEC.BAT on the Edit Entry Panel. Or you can specify which environment (host or workstation) should be used to edit a data set. With these options, one of four editing situations can occur:

Edit a host data set on the host
Edit a host data set on the workstation
Edit a workstation file on the host
Edit a workstation file on the workstation.

Edit a Host Data Set on the Host: The editor searches the ISPF libraries in the designated order to find the member and copy it into working storage. If you specified a nonexistent member of an ISPF library, a new member is created with the specified name.
When you save the edited member, the editor places or replaces it in the first ISPF library in the concatenation sequence, regardless of which library it was copied from.
Edit a Host Data Set on the Workstation: The editor searches the ISPF libraries in the designated order to find the member and copy it into working storage. The data set name is converted to a workstation file name, and that name is appended to the workstation's current working directory. The host data set is transferred to the workstation, and the working file is then passed to the user's chosen edit program.
When you finish the edit session, the working file is transferred back to the host and stored in the first ISPF library in the concatenation sequence.
Edit a Workstation File on the Host: The editor searches the workstation files to find the desired file and copy it into working storage. The workstation file name is converted to a host data set name, and, if greater than 44 characters, it is truncated to be 44. The workstation file is transferred to the host, where you can edit it.
When you finish the edit session, the working file is transferred back to the workstation and stored.
Edit a Workstation File on the Workstation: This edit proceeds as it normally does on your workstation.

Note: Some file names are reserved or restricted depending on the workstation operating system. An attempt to edit a file name that is reserved or restricted by your operating system might cause your workstation operating system or host system to hang. See your workstation operating system documentation to learn restricted or reserved file names.
