Setting default parameters for a box:

You can use the POSITION and SIZE commands to set default parmeters for a box.

Instead of: 
/: BOX XPOS '11.21' MM  YPOS '5.31' MM  HEIGHT '10' MM WIDTH '20' MM INTENSITY 10 FRAME 0 TW

You can write:

/: POSITION XORIGIN '11.21' YORIGIN '5.31' MM
/: SIZE HEIGHT '2' MM WIDTH '76' MM
/: BOX  FRAME 10 TW INTENSITY 10

This can be usefull if you gave several boxes that share the same parameters.

If you want to set the position realtively to the window use POSITION WINDOW
to set the position to the top/left start of the window. Then use POSITION 
to set the current position relatively to the start of the Window. 

Note that you uses "+" or "-" in the ORIGIN position to the set the position relatively.

/: POSITION WINDOW
/: POSITION XORIGIN '+5' MM  YORIGIN '+10' MM

the position is now 5 MM from the left and 10 MM from the top of the window

NOTE: After using the position command you can move the current position

realtively to the last used position

/: POSITION XORIGIN '+10' MM  YORIGIN '+20' MM

Now the position will be X = 15 and Y = 30
 

Drawing a line. You can draw a line by setting the Height or Weidth to 0
and add a frane. E.g. a horizontal line:

/: SIZE HEIGHT '0' MM WIDTH '200' MM
/: BOX FRAME 10 TW XPOS '11.21' MM YPOS '14.81' MM INTENSITY 100
