Thanks a lot for the explanation.
So, just to let you know why I was asking about that...
We create the condor submission file in our application from info in a
config file, which we parse with python ConfigParser.
I was just wondering if I could create the entire globusrsl line using
interpolation, and having a default value for all possible GRAM variables.
Like...
foo=<default_foo>
var=<default_var>
globusrsl = (%(foo)s) (%(var)s)
Interpolation only works if all fields have some value.
Thanks a lot for your prompt responses.
Jose
