Roll Through Dynamic Variables On A Single Commandline Exe Programmatically?

we currently use our own 3rd party customer management system that is cloud-based. They offer pretty good reports; however, we need special reports and the only way to do this is to download our database though web services that the vendor offers. I have some education and experience with programming, but it has been a while. Instead of having to actively engage the webservices directly, our vendor has offered a stepping stone. They have a command line exe that interacts with the webservices and, with the use of different parameters, gets us to the point of having all the data downloaded in xml, csv, or screen printed - the only problem is that it will only do this a table at a time and there are 43 tables I need to interact with. I need to build something that can either be a console application or something that can be run automatically in the middle of the night when there is no load on the server.

Here is what I need to happen:

The command is CMSDownload.exe. It needs to login (again, there are already parameters set up to do this so I can hard code that into the script) Once logged in, the script needs to check a parameter that has been saved that signifies the last date of successful completion. (Obviously, it needs somewhere in the code to place this parameter also). As I mentioned before, each table needs to be downloaded into its own xml file individually. For instance, the following is one example of a table being downloaded in this fashion:

Generate an XML file of all of the data in the accounts table between '01/15/2009 09:13:34 AM' and 01/16/2009.CMSDownload -d somedn -u someusername -p somepassword -f c: empaccounts.xml -m xml -o all -t accounts -s 'start date' -e 'end date'
-d is a login component (credentials)
-u is a login component (username)
