You can provide a description of an object when you are creating it with a create command.
Whenever you use a create command to create an object, you can describe the object in a 50-character field on the TEXT parameter of the create command. Some commands allow a default of *SRCMBRTXT which indicates the text for the object being created is to be taken from the text of the source member from which the object is being created. This is valid only for objects created from source in database source files.
If the source input for the create command is a device or inline file, or if source is not used, the default value is blank. This text becomes part of the object description and can be displayed using the Display Object Description (DSPOBJD) or Display Library (DSPLIB) command. The text can be changed using the Change Object Description (CHGOBJD) command or many of the Change (CHGxxx) commands that are specific to each object type.
