The parts of a line have the following syntax:
Tag: (gggg,eeee)
with gggg and eeee are 4 character hexadecimal values
representing group and element tag. Spaces and Tabs can be
anywhere in a Tag specification
VR: Value Representation must be written as 2 characters as in
Part 6 of the DICOM standard. No Spaces or Tabs are allowed
between the two characters. If the VR can be determined from
the Tag, this part of a line is optional.
Value: There are several rules for writing values:
1. US, SS, SL, UL, FD, FL are written as decimal strings that
can be read by scanf.
2. AT is written as '(gggg,eeee)' with additional spaces
stripped off automatically and gggg and eeee being decimal
strings that can be read by scanf.
3. OB, OW values are written as byte or word hexadecimal
values separated by '\\' character. Alternatively, OB or OW
values can be read from a separate file by writing the
filename prefixed by a '=' character (e.g. '=largepix.dat').
The contents of the file will be read as is. OW data is
expected to be little endian ordered and will be swapped if
necessary. No checks will be made to ensure that the amount
of data is reasonable in terms of other attributes such as
Rows or Columns.
4. UI is written as '=Name' in data dictionary or as unique
identifer string (see 6.), e.g. '[1.2.840.....]'.
5. Strings without () <> [] spaces, tabs and # can be written
directly.
6. Other strings with must be surrounded by [ ]. No bracket
structure is passed. The value ends at the last ']' in the
line. Anything after the ']' is interpreted as comment.
7. '(' and '<' are interpreted special and may not be used when
writing an input file by hand as beginning characters of a
string. Multiple Value are separated by '\\'. The lines need
not be sorted into ascending tag order. References in DICOM
Directories are not supported. Semantic errors are not
detected.

Command line options are distinguished from parameters by a leading '+' or '-' sign, respectively. Usually, order and position of command line options are arbitrary (i.e. they can appear anywhere). However, if options are mutually exclusive the rightmost appearance is used. This behaviour conforms to the standard evaluation rules of common Unix shells.
In addition, one or more command files can be specified using an '@' sign as a prefix to the filename (e.g. @command.txt). Such a command argument is replaced by the content of the corresponding text file (multiple whitespaces are treated as a single separator) prior to any further evaluation. Please note that a command file cannot contain another command file. This simple but effective approach allows to summarize common combinations of options/parameters and avoids longish and confusing command lines (an example is provided in file share/data/dumppat.txt).
The default behaviour should be preferred and the DCMDICTPATH environment variable only used when alternative data dictionaries are required. The DCMDICTPATH environment variable has the same format as the Unix shell PATH variable in that a colon (":") separates entries. The data dictionary code will attempt to load each file specified in the DCMDICTPATH environment variable. It is an error if no data dictionary can be loaded.
