John,

Begin with a process flow diagram, build an ERD and design the database BEFORE you bother with the UI presentation. I've actually written a program back in my VFP 3.0 days that did this very thing. Unfortunately, the employer who has the code went belly-up.

In the system that I designed, every program was accounted for separately - providing instruction on running the program. Then, I had a jobs table that had the desired programs referenced in the sequence that they were to be run and special overriding instuctions as needed. In the environment that I worked in, a program may be used multiple times during a given evening shift - depending on the processing needs. These jobs were then assigned to a specified schedule / interval. (e.g. every Wednesday, every third Monday, last business day of the month, end of quarter, etc.)
Also, I believe that these jobs had a sequential order with dependencies.

Good luck.
Doug

Also I need to select the type of run of the job, "Regular", "Combo", or "Split" preferably from a drop list selection. I also need to add comments, trigger events and perform validations, etc. for every job/line added.
