3 Powerful Commands for the iSeries
Here are 3 powerful commands that you can add or probably use more effectively in your tool list. (You probably already DO! I'm learning still.) Getting to use them effectively is the key. There is lots of detail to be had.
- DSPFD - Display File Description
- DSPFFD - Display File Field Description
- DSPDBR - Display Database Relations
I haven't used the DSPDBR command much. The other two can really help you find out lots of information about a file. You can determine how many records, how many members. The file format level identifier # can really help. It is what is evaluated in a level check. (Another whole post in itself.) You can learn where the file is located, in what library. You can determine how many instances of a file there are.
I have only briefly touched on the these commands. In parts 1-3 I will delve deeper into the commands and how they can be maximised.
