       C.P.M. also allows you to SELECT objects by CROSSING the edge-line of a WINDOW through a line.  This is particularly useful if you want to alter a pattern with the STRETCH command.


    During the following set of instructions commands will be written in CAPITALIZED BOLD letters (ie.: MOVE, PLINE, REGENerate).
Some commands are typed in as abbreviations of words.   
    Additionally, some COMMANDS  appear in sequential "strings" of commands that are made up of a series of optional steps (for example:
    Close/Join/Width/ Edit vertex/Fit curve/Spline curve/Decurve/Undo/eXit <X>:).  
These may be TYPEd on the keyboard as a single letter followed by ENTER or may be SELECTed from an on-screen menu with the cursor device.
    In these directions the single letter or partial word commands that may be typed will be written as follows: W(IDTH) or NEAR(EST).  The bold letters are the part of the command that needs to be typed to give the command and the rest of the word that it stands for following in parentheses.  It is often easier to remember single letter commands when you think of them as standing for a whole word.  (example: C(LOSE)= the C is what you type and it stands for CLOSE, which is the function you want to perform.)  
    When the command word is the same as the action you are taking, the part of the word that is the command will be bolded, capitalized and fully spelled out with all the command letters while the modifying letters of that word are in lower case.  This leads to words that are not correctly spelled, but the learning process is better served by having the command name emphasized.  (example:  MOVEing, ERASEing, TYPEing, etc.)


    To choose a command from the on-screen menu, move the cursor device so that the CROSS-HAIRS on the screen move toward the menu on the screen until they disappear.  You will see a rectangle of HIGHLIGHT appear some where on the menu, probably in a position horizontally even with the last point on the screen where the CROSS-HAIRS disappeared.  By moving the mouse up and down, you can move the HIGHLIGHT to frame the various commands.  When the HIGHLIGHT is on the command you want to use, CLICK the SELECT button on the cursor device to choose the command.  

    To activate a command, one must follow a command with ENTER.  The MENU has been designed so that when you SELECT a command from the menu it is automatically ENTERed.  When you type the sub-command, you need to follow it by typing the ENTER (RETURN) key or CLICKing the ENTER button (right button on the mouse) on the cursor device.

    Some commands that are made up of a series of steps are only stopped by CLICKing or typing ENTER. You will also discover that clicking the ENTER button on cursor device is a time and gesture saving method for ending sequential commands.  This is a useful habit to
