      B.   Activity analyzer


           The activity analyzer, Activan, is a facility which monitors the
      execution  of  a Pascal program and prints a graph showing the amount
      of time spent executing each portion of the program.  To use Activan,
      a program must be compiled with  the  %LTRACE  directive  or  the  $L
      compile switch on.

           Activan  monitors  the  line  numbers  as a program executes and
      keeps counters for the line numbers in the specified range. The range
      of line numbers to be monitored and the line spacing can be  set  and
      changed when the program is running.

           To  run  a  program with Activan, specify the $A switch when the
      program is started with the EXEC command:

                  EXEC TEXTPGM  $A


           Before  the  program  begins  execution,  Activan  will  request
      console  input to specify the line range to be monitored and the line
      spacing.  When  those  parameters  have  been  entered,  the  program
      execution will begin.

           If  Activan  is active when the program terminates, Activan mode
      is entered so that a final histogram can be printed.

           While the program is running, it can be interrupted and  control
      returned  to  Activan by keying in a control-A command.  Activan will
      then request which action is desired:

                 code   action
                 ----   -------
                  C     clear the counters to zero
                  H     print histogram of activity
                  I     initialize the line range and spacing
                  M     run the program with Activan monitoring
                  W     run the program without Activan
                  Z     terminate the program
