A couple of points... Variables: I have never had a problem with the concept of Display Only fields as variables. I have worked on VB and C applications that had so many variables defined you needed a spreadsheet to keep track of what was done where. I have worked with Remedy applications with so many D/O fields you got lost. I have worked on other Remedy applications with only a few D/O fields that were reused. It all comes down to design. You can always tell a good well thought out design against something just slapped together.
Debugging: In the 7.5 beta announcement David listed "A text based debugger for server side workflow" Source Code: It could be handy at times, but not having it actually worked in my favor one time. I had a manager (who didn't even use the system) that wanted to check my code. I gave him a .def file to shut him up (He wasn't my manager).

That topic is of the power of ARS for development. While I agree that ARS is great, I would have to qualify that to say that if you want to build an application that is within its capabilities, it is great. However, having worked with Visual Basic, PHP, Perl, and a few other things, I see plenty of limitations in ARS as a development tool. For example, there is no such thing as a variable in ARS. Yes, you can add a field to a form, even a Display Only field, but you can't instantiate fields during runtime on the fly. You have to purposely create fields for usage later on, and this limitation causes us to often re-use certain fields as generic variables, which can make troubleshooting difficult sometimes. I've worked on a system that someone else built that I had to troubleshoot something on a field that had many different Set Fields actions occurring at different points with different tables. It was definitely possible, but since ARS is missing another major capability that most development platforms have. ARS doesn't have a way to step through code. We can't start up processing on a form, and pause it to see what is going on. All we can do is 1) go through log files and recreate the workflow in our minds, or 2) pop up messages after each piece of workflow we want to troubleshoot. If there was a way to step through each piece of workflow that is running, that would be a tremendous help to us. Another issue that is more of a matter of taste I guess, is the inability to generate flat source-code. Yes, I have learned to read .def files to some extent, but it should be easier to read. Instead of values like " 4\1\1\179\2\4\32\Change Level IA - Implementation\" in workflow, the definition files should display what we see in the Admin tool. These are the somewhat major problems I have with ARS for development. If you want to build an application with a database back end, a web interface, and have most of the standard controls (save, search, displaying tables, etc) just work automatically, ARS is a great too. There isn't anything out there that I've worked with which can top ARS development in terms of speed. In some cases, you do have to make sacrifices for more complex functionality, but it's still a great development platform for what it does. I just wish BMC would change the things I mentioned above, plus a few other minor ones (I'd like to be able to use arrays if they implement variables, I'd like to be able to have workflow triggered off of typing in specific fields, not just pressing enter and gain/lose focus, etc.) What are your thoughts about the pros and cons of ARS as a development tool? Perhaps we can put all of our heads together and go back to BMC and tell them what we want, plus come up with enough positive things about it to show our clients and employers that ARS is a great development tool.
