B.2. Working with the history window

Every statement you enter is copied by BioBIKE into the History Window, appearing as something like:

<4>> (LENGTH-OF ssr1600)
:: 351

Each statement is numbered sequentially from the top of the window and is followed by :: and the result of the statement. You can exploit these features in several useful ways:

• Copy a command
  Clicking on the number associated with a statement causes that statement to reappear in either the Command or Program Window (BioBIKE chooses according to the size of the statement). This is quite useful when you want to repeat execution of a command or to edit it.
   
• Copy a result
  Clicking on the double-colon assicated with a result causes that result to reappear in either the Command or Program Window.
   
• Refer to a result
  You can use a previous result within a new statement with the RESULT function. For example:

  (DISPLAY-LINE "The length of the gene is " (RESULT 4))

  Especially if you generate long lists (like a list of all genes of Synechocystis), your history window will grow to a size that can become a burden. The larger the window, the longer it will take for your screen to load when you contact BioBIKE. At some point, you'll probably like to junk all or some of the window. You can do this with the CLEAR-HISTORY command.
  
  Your History Window is automatically saved and retained for a period of time (currently 90 days). You can click on Session Logs at the bottom of the screen and bring up the History Window of any session within that period. You download your History Window to your own computer as a permanent record of what you've done simply by saving it through your web browser.
