6.30

• Enhancements on user interface

    • Before Undo and Redo are possible only for changing drawing area and window size, but support them for the change of Function, Note, Line & Polygon
  • Script execute faster than before
  • Support for error check when making scripts
  • Objects (functions, figures, and so) are displayed in order of construction process. This order can be changed by dragging with mouse.
• Enhancements on presentation
  • In "the presentation mode" which allows double size font of statements and parameter value, you can switch to the normal mode after starting GRAPES.
  • Added half line and arc for Line & Polygon
• Enhancements on function
  • Enhancements of the functionality of intersection between two lines given by functions, to the intersections for line and circle, and for two circle.
  • Added a function which gives a point of contact of the circle (by the tangent passing through a point exterior of the circle: "Vcos"
  • Added a function "roll" which gives the position of a point on the unit circle.
  • Support 3 arguments, x, y, z for user function
  • Support 8 user functions in the place of 5
• Bugs fixed
  • A bug was fixed that the file containing period in its name was not saved correctly
  • A bug was fixed that the recursive script was not stopped by F1

6.23

• Enhancements on user interface
  • can drag correctly a point on the grid by pusshing Ctrl key while dragging an elementary object
  • can redraw while dragging an elementary object or a point on curves
  • can easily show the length of a segment and the angle measure
• Enhancements on presentation
  • By starting GRAPES with Shift key or Alt key pushed, expression and parameter values will be shown in double size font (presentation mode)
  • added a button on the scale palette, which allows to change easily scale font and thickness of axis by four levels
• Bugs fixed
  • A bug was fixed that stuck error was given when x or y are substituted in the polar equation
  • A bug was fixed that graphs was not diplayed correctly when changing "display off" >> "change area" >> "display on" at the same time when existing an after-image of implicite funtion.
• Enhancements
  • Scale indicator will be placed to be kept off from grid line when it existes, and to be at the center when it doen't existe.
    • As older version, the position can be fixed
  • By pushing the parameter button all the time, the parameter increases (decreases) a little by little. In the old version, when the script is started automatically, the increase is just for one time. This functionality is changed to be increased continuously, for all the time.

6.22

• Enhancements on user interface
  • Support for the drug of point on any curves
  • Support for nesting of script
    that is, support for calling other script from a script
• Bugs fixed
  • Display switch of segment was not registered in the file
  • The after-image of curves was not displayed when changing display area and was not printed (Bug only for 6.21b)

• File compatibility
  • The 6.22 version files are not supported for older vesion GRAPES
  • Support files of after 5.60 version

6.21b
Bugs fixed

• A part of the system resource was not sometimes opened, when using fulfill color in polygons and curves.
• DGI resource was not sometimes opend, when using fulfill interior of curve by hatching pattern.
  • Explication: System resource and GDI resource are so called Windows Resource. They are indipensable for executing system and application. On the system NT/2000/XP, they are proportional to the size of memory. But the system 95/98/Me has only 64KB. Therefore, these bugs will often occur on the system 95/98/Me.

6.21

• Enhancements on presentation
  • Added deep color line and grid point to grid type
    When selecting thick line for axis, the scale will be also thick
  • Allows to show message in the function "Pause" of script: "Pause (message)"
  • Change a part of vector functions in Japanese representation
• Bugs fixed
  • like "-Sqrt a sinx", when the argument of "-Sqrt" is used without bracket and the multiplication without sign, GRAPES did not calculate correctly.
  • when changing the grid type to dotted line, angle measure changes automaticaly to radian measure

6.20

• Enhancements on user interface
  • Support for vector
    • support for vector in the expression without restriction
    • support for writing a point position of Elementary objects and Curve by vectors
  • Added Metafile and JPEG formats for Save Image
• Enhancements on presentation
  • Give property for the origin point
    • can edit label and put a point
  • Added angles for Line & Polygon
  • four types of regions can be used for painting interior part of curves
  • Added a function to script, which allows to control Hide/Show of objects (ShowObj,HideObj,InvShowObj)
  • Added a function to script, which allows to delete after image of objects one by one: (ClrAimg())
• Add functions
  • Support for operators for vectors
    • addition, substraction, multiplication, inner product, etc.
  • Added functions for vector
    • dividing point, intersection, foot of the perpendicular$BJ,E@!$(B

    • support absolute value sign for vector
• Bugs fixed
  • Using dot line for scale grid makes the drawing slow (bug of version 6.16)
  • In some machines, graph window is not displayed correctly (bug of after version 6.00)
  • When printing a window, one dot is shifted from a correct place.
  • After right clicking on a draggable object and appearing a pop up menu, point moves by left clicking on other point.
• Modification
  • stop supporting Px, Py, and Pr expressing objects of figure. Use P.x, P.y, and P.r for expressing objects or elements of a vector
  • Change of script commands
    • stop supporting Px, Py, and Pr of On Change statement of script. Use On P Change
    • Changed "ShowAimg" to "Refresh"
