ACQ - Execute Advisory

      The ACQ Program Execute Advisory Menu:

• Acquisition
• [4] Start
• [5] Stop
• DataLog
• [7] New File
• [8] Save Data
• Misc
• [9] Wait

         The 'Execute Advisory' submenu items each have an
      advisory code number.  An external program can control
      the acquisition process by using the Dynamic Data Exchange
      protocol (DDE).  The commands are of the form:

               Advisory = #
      
      where # is any valid advisory code number.  The DDE link
      topic is AcqF.

		   More information about the DDE option can be found
      in the configuration of the DDE Link section.

         Clicking on the 'Acquisition' menu item displays the
      extended menu:

         With data acquisition not in progress only the
      'Start' submenu item is enabled.  Clicking on this item
      is equivalent to clicking the 'Start' button on the main
      window.  While data acquisition is in progress the submenu
      item 'Stop' will be active.  The 'Stop' submenu item is
      equivalent to the 'Stop' command button on the main window.

         Clicking on the 'DataLog' menu item displays the
      extended menu:

         The 'DataLog' items control the writing of histogram
      data to a file.  Normally a datalog file has already been
      opened using the File > Open DataLog File dialog.  If a
      file has not been opened then the first click on subitems
      'New File' or 'Save Data' will open a file on your system
      drive as 'D:\Data\datafile.001'.  If the file already exists the
      extension will be incremented until a new file can be
      created.  Existing files will not be overwritten.

         Clicking the 'New File' submenu item will create a new
      file having the same name but incrementing the extension
      by 1.  If the file created with the File > Open DataLog File
      dialog has a non-numeric extension then the extension is
      set to 001.  If the file already exists the extension will
      be incremented until a new file can be created.  Existing
      files will not be overwritten.

         Clicking the 'Save Data' submenu item appends the current
      data to the data file.  Subsequent 'Save Data' clicks will
      continue to append data to the same data file.

         Clicking on the 'Misc' menu item displays the
      extended menu:

         Clicking on the 'Wait' submenu item brings up a
      message box:

         The message box requires user intervention before any
      further operations can be performed.  Data acquisition is
      suspended and all Advisorys are blocked until the
      'OK' button is clicked.
