The menu button labelled "Stream 1" allows the user to choose the name
of the
output device.
This must be set correctly before the sort is started.
The current set of output 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 check button labelled "Use input filenames to name output files"
should also be set to the desired mode.
If unchecked (no tick) then the list of runfiles defined in the output
handler window is used.
Each output runfile is filled before going on to the next one in the
list.
If checked (ticked) then one runfile needs to be defined for each
output tape (or disc directory) required.
These are used as a template, with the file name part being
overwritten
by the name of the input file.
As each input runfile is started, the current output template is copied
and the input filename is inserted into the list.
If the input filename is not a unique name ( i.e. a wildcard) then the input tape volume name is used instead.
For tape output the transferred input filename is stripped of characters
not allowed in ANSI format filenames (e.g. underscores) and then
truncated from the front if longer than 6 characters.
