+>&#13;The following options for displaying cycle counts in listings are provided.
+These options are enabled from pragmas on the command line or in the
+assembly files themselves.  For compatibility with other assemblers you can
+use the "OPT" keyword in addition to "PRAGMA."</P
+><PRE
+CLASS="PROGRAMLISTING"
+>opt c  - enable cycle counts: [8]
+opt cd - enable detailed cycle counts breaking down addressing modes: [5+3]
+opt ct - show a running subtotal of cycles
+opt cc - clear the running subtotal</PRE
+><P
+>&#13;The assembler supports both 6809 as well as native-mode 6309 cycle counts.
+In 6309 mode the counts are displayed in parenthesis instead of brackets. 
+In addition, some operations have a variable cycle count.  In this case a
+"+?" is displayed to alert the reader.  Sample output is shown below.</P
