Clear memory and TSR from DOS command prompt

I need some info on how to clear the memory or TSR's within my command prompt. I run a batch process within a command prompt, and that batch process calls a GroupWise API. So, this batch process is not completely DOS. It calls an API which is Windows based.

I would like for the batch process calls the GroupWise API repeatedly, but when I do I want it to have different account logons. However, this is difficult to do because the last "call" stays open in memory. So, I can't call it again within the same command prompt.

What command line tool do you recommend that I can run after each command I execute? I hope there is a command line tool that will flush out all TSR's and anything left open in memory. Is there such a tool? This is what I am looking for so if you know of a tool that will clear out my command prompt memory and anything left running then please let me know what it is and where I can download the program.

I use to use MARK and RELEASE. Here's a reference to a site that has these tools:

Summary:       TSR memory managmt utils (MARK/RELEASE/MAPMEM)

The way it works is you run MARK and then run the processing that installs the TSR and does the processing.

When the processing is complete you run RELEASE and it releases the memory consumed by the TSR's and restores the interupt table.

You might also check to see if the TSR's involved in your processing have an unload feature. Some do it like this:

program /u

Good Luck,
