As explained in Filesystems and Files on the AS/400, the AS/400 supports multiple file types. We will focus on database files in this article, though.
Stream Files
The AS/400 permits green-screen editing of stream files in the IFS with the edtf command. Enter EDTF in a command line and press F4 to learn about parameters.
Source Files
Members of source files are edited with the Source Entry Utility (SEU)[1]. Since SEU requires manual declaration of Library, File and Member to edit, it's more often indirectly invoked with a command part of PDM[2], WRKMBRPDM.[3] This command provides one with a member list of a chosen source file and thus makes it easy to navigate between members.
Database Files
There are basically 2½ ways to edit (or view) database file contents:
- Create a DFU program with
STRDFUwhich directs you to the appropriate menu and- allows some possibilities in UI design via item 2,
- Create a throwaway temporary DFU program which gets deleted after using via item 5,
- Use the AS/400 facilities to Program an Application yourself. This sounds a lot more complicated than it is.
