You can select the system files to be used for the unload function from a list.
You can produce this selection list from an object specification screen of the unload function when performed in advanced-user mode.
The instructions below are an example of using the function when unloading Natural library objects.
To select a system file from a list
On the Unload Natural Library Objects screen, choose Select DBID/FNR or choose PF5 (DBIDs).
The Select System File window appears where the system files available in the current Natural environment are listed with their directory path names (Path), database IDs (DBID) and file numbers (FNR).
Select the system file you want to use for function processing by entering any single character in the Sel column next to the system file required.
If you select FNAT/FUSER (selected by
default), all libraries contained in the current FNAT and FUSER system files
are used.
The database ID and file number of the system file selected are entered in the DBID/FNR fields of the Unload Natural Library Objects screen. If you selected the default system file, these fields remain empty.
