+The following syntax demonstrates two different ways to label the rows
+and columns of a matrix with @code{PRINT}:
 
+@example
+MATRIX.
+COMPUTE m=@{1, 2, 3; 4, 5, 6; 7, 8, 9@}.
+PRINT m/RLABELS=a, b, c/CLABELS=x, y, z.

+COMPUTE rlabels=@{"a", "b", "c"@}.
+COMPUTE clabels=@{"x", "y", "z"@}.
+PRINT m/RNAMES=rlabels/CNAMES=clabels.
+END MATRIX.
+@end example
+
+@noindent
+With @code{MDISPLAY=TEXT} (the default), this program outputs the
+following (twice):
+
+@example
+m
+                x        y        z
+a               1        2        3
+b               4        5        6
+c               7        8        9
+@end example

+@noindent
+With @samp{SET MDISPLAY=TABLES.} added above @samp{MATRIX.}, the
+output becomes the following (twice):
