                   General ALADDIN Glossary
                   ------------------------

HELP ?
To query the ALADDIN dictionary for a character string, type the string
followed by a question mark. A description of the contents of this
dictionary file can be viewed by entering DICT followed by a question
mark.

For a summary of ALADDIN interactive commands use the command "H"

DICT ?
 This dictionary defines the meaning of special symbols used to create
ALADDIN entries and also contains all the current IAEA Boolean labels.

-----------------------------------------------------------------------

$ ?
The "$" symbol, in column 1, denotes the start of an ALADDIN entry.  The
"$" character, with optional suffix, is taken as the access label.  A
blank access label suffix means that standard ALADDIN entry routines are
to be used. The "$" symbol with, optional suffix, is folowed by the
blank delimeted hierarchical labels.

& ?
The "&" symbol denotes the end of the hierarchical and the start of the
Boolean labels.

# ?
The "#" symbol denotes the end of the labels fields. The "#" symbol,
with optional suffix, identifies the evaluation function which is used
by ALADDIN to generate numeric data values from the information in the
coefficient field which follows.

! ?
The "!" symbol, entered in column 1, of a line identifies that the
information on the remainder of that line are comments for the
particular entry.

REC ?
Data recommended by IAEA Atomic and Molecular Data Unit
