Perhaps the most noticeable `feature' of CCDPACK programs is their ability to
accept, and process, lists of data files and other associated parameters,
such as exposure times and position list names (see
``using position lists'').
A list of `names' can be supplied in
response to one prompt, or can be supplied on successive lines using the
continuation character `-' to force a reprompt for more
specifications. A list of names consists of a series of character
strings separated by commas. Note that the list itself is really a
string not a vector and should be enclosed in quotes "".
The quotes are not necessary if the list consists of only one name, or if
given in response to a prompt. When using the C-shell it is necessary to
protect the "" so that the final string passed to the application
still contains these (so a suitable response would be '"ndf1,ndf2"').
