We have a model in SS 3.30.14 with generalized size comp data. When
  we examine the data_new.ss file, there is a line added below where you
  input your size frequency bins that reads "Note: negative value
  for first bin makes it accumulate all smaller fish vs. truncate small
  fish" that is not commented out. This means that we have to
  manually go through the new data file, if we are using it, and comment
  that line out. It is especially problematic when trying to bootstrap
  the model because then we have to open every new datafile and comment
  the line out manually so that we can run the bootstrapped model. I've
  attached the data_new.ss file that shows the problem line (line 599 is
  the first instance).
