Comparison of Approaches

Single-Procedure Approach	Multi-Procedure Approach
Multiple secondary dialog boxes	One detail version with disable flags
LIST and MAINTAIN in one procedure	LIST and MAINTAIN in at least two procedures
Menu items disabled according to function	Push buttons disabled according to function
Selected object used as a listbox on the appropriate dialog boxes	Select list occurrence moved to the output field and view-matched to the input field of the called procedure

These are situations where several procedures may be preferred to a single procedure:

Processing associated with a dialog box needs be performed before it is displayed, for instance, to display a value that is derived or computed from primary window input as an output field.
The procedure is too large and should be divided into more manageable units.
