Starting with object generation 5.12, you can store fit parameter sets in a list called ‘Fit parameter pool’.  This list is stored as part of the SCOUT or CODE configuration file. Using fit parameter sets from the pool avoids the necessity to load them from separate files.

Instead of specifying a filename for the fit parameter set (which is still possible) you can use phrases like ‘pool(step 1)’ or ‘pool(oscillator strengths only)’ to load fit parameter sets with names ‘step 1’ or ‘oscillator strengths only’.

Using file based fit parameter sets is possible after all, of course.
