+/ONE OF THE REASONS WHY TECO GETS SO MANY OPERATIONS
+/INTO SUCH A SMALL AMOUNT OF CORE IS THAT IT
+/IS FULL OF *K*L*U*D*G*E*S*. THESE SHOULD BE KEPT IN MIND WHEN
+/MODIFYING THE PROGRAM. SOME OF THEM ARE:
+
+/ THE "SORT" ROUTINE COMPARE LIST MUST END WITH A NEGATIVE NUMBER.
+/ USUALLY A FORTITUOUS JMS OR OPR INSTRUCTION IS USED
+
+/ THE "SORT" JUMP LIST ENTRIES ARE TREATED AS JUMP ADDRESSES
+/ IF THEY ARE POSITIVE AND SUBSTITUTE VALUES IF THEY ARE
+/ NEGATIVE - THEREFORE ALL LOCS JUMPED TO MUST BE BELOW 4000
+/ ANOTHER CONSEQUENCE IS THAT "QUOTST" CANNOT BE CALLED FROM
+/ ABOVE 4000
+
+/ THERE ARE OTHER LOCALIZED KLUDGES - THEY CAN GENERALLY
+/ BE IDENTIFIED BY THE APPEARANCE OF A DOUBLE-ASTERISK IN THE
+/ COMMENTS FIELD ALONG WITH A TERSE DESCRIPTIVE COMMENT
