+The\verb|\Arrayij| and \verb|\Arrayijk| commands may, of course, be
+placed as arguments of \verb|\def| commands.  They, cannot, however, be
+placed into an \verb|\edef|.  If the user has need to place the
+array-element content into an \verb|\edef| (and assuming that the
+actual array-element content is suitable for an \verb|\edef|), the
+following approach may be employed.  The contents of an array which
+would otherwise be accessed by the command
+{\itshape\vb|\Arrayij{|identifier\vb|}{|row\vb|}{|column\vb|}|\upshape}
+can be accessed directly with the command
+``\itshape\vb|\|identifier\vb|X|roman-row\vb|X|roman-column\upshape'',
+where \textit{roman-row} and \textit{roman-column} indicate that the row
+and column numbers are expressed in lower-case roman numerals.  Thus,
+even if \textit{row} and/or \textit{column} are obtained by way of a
+mathematical calculation, they can be placed into an \verb|\edef| token
+using the following syntax:\\
+  \rl\itshape\vb|\edef\tokenname{\csname %|\\
+  \rl\rl\rl identifier\vb|X\roman{|row\vb|}X\roman{|column%
+  \vb|}\endcsname}|\upshape\\
+For 3-D arrays, the corresponding command is 
+``\itshape\vb|\|identifier\vb|X|roman-plane\vb|X|roman-row\vb|X|%
+  roman-column\upshape''.
+Therefore, the \verb|\edef| may be accomplished via\\
+  \rl\itshape\vb|\edef\tokenname{\csname %|\\
+  \rl\rl\rl identifier\vb|X\roman{|plane\vb|}X\roman{|row\vb|}X\roman{|%
+  column\vb|}\endcsname}|\upshape\\
+Note, however, that no error bounds-checking is performed when command
+syntax such as 
+``\itshape\vb|\|identifier\vb|X|roman-plane\vb|X|roman-row\vb|X|%
+roman-column\upshape'' is employed.
