Are you sure the syntax is

  $$([$(process)+1])

The example in the manual says

  The syntax appears as:

  $$([ClassAd expression])

and the example given is:

  In the submit description file will be

  arguments=--memory $$([TARGET.Memory * 0.9])

suggesting that, if it can be done, you should be using:

  $$([Process + 1])

without the extra $() around Process.

My other suggestion would be to create a parallel directory of
links to the input files where the link names match what you
appear to need and the link target matches what a program that
could handle "start from 0" would just use without issue.


I should say that I have not tried either of the above.
