This window is handler-specific. It allows modification of runfiles and other changeable parameters.

The menu button labelled Stream 1 allows the user to choose the name of the input device.
This must be set correctly before the sort is started.

The current set of input runfiles known to the sort program are shown in the list window. On selecting one, its contents are copied into the modify boxes in the lower half of the window. Any changes to the list made by using Add, Replace, ResetLine or Remove must be copied back into the program using Save.

The Add button copies the current contents of the modify boxes to the end of the list.
The Replace button copies the current contents of the modify boxes and overwrites the currently selected list member.
The ResetLine button copies the current volume and file name contents of the modify boxes, sets the start and end blocks to zero, and overwrites the currently selected list member.
The Remove button deletes the currently selected list member from the list of runfiles.

The Save button writes back the current runfile list contents into the sort program.

The Config button is only activated if it is necessary to have a configuration for the particular handler (e.g. Euroball input handler).
It enters a configuration window to allow the supply of handler-specific data.
