So it seems, I just tested by starting a program with bogus parameters
including a & character...

But a *very simple* solution to the "problem" is to just enclose the
module name (with the embedded &) in double quotes.
I tested this on the command line and there is a definite difference
when using quotes and not.
You can do this little test yourself:
- in a temp folder create a folder Run&Drive and put some file into it
- Then create a command prompt on the temp folder
- Now issue the command 'dir Run&Drive'
  The result is an error message
- Then issue 'dir "Run&Drive"' instead
  The result is the directory listing we would expect

So by modifying CVSNT such that it supplies the built-in arguments
enclosed in double quotes I think the problem will be fixed. The user
supplied arguments can be controlled by the content of the taginfo
file so these do not have to be handled, even though a general
argument processing function in CVSNT that puts quotes around all
script call arguments that are not already quoted would not harm but
save from future problems.
Windows will strip the quotes away anyway, but they protect against
problematic strings (also names that have embededd spaces...).

Here is the output from my testing:
F:\Engineering\Projects\ModuleYY>dir Run&Drive
 Volume in drive F is Eagle F
 Volume Serial Number is 5064-C593

 Directory of F:\Engineering\Projects\ModuleYY

File Not Found
'Drive' is not recognized as an internal or external command,
operable program or batch file.

F:\Engineering\Projects\ModuleYY>dir "Run&Drive"
 Volume in drive F is Eagle F
