+#PURPOSE: This program finds the maximum number of a set of data items.
+#
+
+#VARIABLES: The registers have the following uses:
+#
+# %edi - Holds the index of the data item being examined
+# %ebx - Largest data item found
+# %eax - Current data item
+#
+# The following memory locations are used:
+#
+# data_items - contains the item data. A 0 is used to terminate the data
