- F1 Program and Drawing Modification
- <r>-allows rotation about a point in the plane of the screen. First select
- center of rotation, next define object. Follow prompts. Rotation can be
- stopped short of the full number of steps by selecting <Esc>.
- *C*-<r> will rotate only the current color as selected by F8. Use <Alt-r>
- to rotate all three colors of an object.
- <a>-again-allows the same object to be rotated again with a new angle.
- <R>-revolves an object about a horizontal or vertical axis. Use like <r> by
- marking axis center, and any two opposite corners.
- <Ctrl-r>-rotates left half of screen 90 degrees.
- <z>-zooms an object either up or down. Does not change drawing scale. Use like
- <r> by marking center, and any two opposite corners.
- *C*-will zoom only current color as selected by F8. Use <Alt-r> to zoom
- entire object.
- <Z>-zooms the entire screen up or down, changing scaling accordingly.
- <m>-mirrors image of an object defined in box. Select mirror line orientation.
- <M>-mirrors entire screen either horizontally or vertically.
- <F>-flips/rotates full screen through desired view angle.
- <v>-reverse video.
- <g>-grid, can be used to remove grid by first selecting F8-dark. *C*-<0>
- <c>-removes correction check normally occuring after each function. Selecting
- <c> again returns error check.
- <n>-exits function.
-
- F2 Draws a Box.
- <d>-display-displays box as cursor is moved
- <s>-produces shaded box with choice of light, medium, and heavy shade
- Use F8 to set color. Mark TLC and BRC
- <D>-same as <d> only box is copied for use with F7 animate, move, etc.
- <S>-same as <s> only box is copied for use with F7 animate, move, etc.
- <n>-exits box drawing.
-
- F3 Draws a circle, ellipse, or arc.
- <c>-circle-draws a full circle. The location of the cursor when <c> is selected
- will be the center of the circle. After marking the center, move the cursor
- to the desired radius. The length of the radius is shown on the prompt line
- and the circle is displayed. The center can be shifted with the numeric keys
- corresponding to the cursor keys. Select F3 again to mark the radius and
- draw the circle. If circle is not of desired roundness, select <$> and
- change screen aspect ratio.
- <a>-arc-draws an arc using cursor position as start and end. As with the
- circle, the current cursor position is the center of the arc. The second
- position is the radius and one end of the arc. The third position is the
- other end of the arc. Arcs are always drawn counterclockwise.
- <e>-ellipse-draws a full ellipse. Use as with circle, but use up and right
- arrow to properly shape ellipse before hitting a return.
- <n>-exits function
- While in the CURSOR MODE, selecting <C> exchanges the present cursor position
- with the last center of a circle, arc, or ellipse.
-
- F4 Shades area
- <l>-lightly shades enclosed area
- <m>-medium shading of enclosed area
- <d>-dark/heavy shading of enclosed area
- Use F8 to determine color of shading
- <s>-Spray paints area. Use on painted circle to give a 3-D effect. Effects
- active color only. First draw item and paint with F5. Current cursor
- location sets the position of light source (generally on the object).
- Next mark any corner of box containing object and select F4 again.
- Mark opposite corner of box and select F4 to spray paint.
- <Alt-s>-as above but effects all colors.
- Set screen aspect ratio to 0 to shade columns.
- To stop shading while in process type <Esc>.
- <n>-exits to cursor mode
-
- F5 Paints the area enclosing the cursor
- Both paint until reaching boundary with same attribute.
- Gaps will cause the paint to leak out.
- <l>-light (on)
- <d>-dark (off)
- <c>-selects color palette
- <C>-selects background
- <n>-exits to cursor mode
-
- *C* -The medium resolution portion also allows the following.

- exit if cursor not in correct position.
- <d>-dot-places dot at cursor location
- A RETURN will mark dot
- <l>-line-connects cursor points with a line. A RETURN will mark next point and
- continue drawing. All points must be marked with a RETURN or they will not
- be saved. Select F6 a second time and <e> or <E> to end line drawing.
- <c>-cursor-draws continuous lines as the cursor is moved.
- <t>-text-enters text at cursor location.
- <p>-parallel-draws parallel lines.
- <s>-spoke-draws lines from common center point.
- <a>-arrow-places arrow head at cursor location either pointing up,down,left, or
- right. Use u or d to upsize or downsize the arrow
- <e>-exit-ends current mode. Required after any of the above except text and
- arrow.
- <E>-ends current mode and saves line drawing to disk using user specified name.
- These are saved as vectors and are ideal for commonly used symbols.
- <o>-old line drawing from disk. A single drive letter will display appropriate
- files on disk. Must specify rotation angle(any angle) and scale factor. A
- RETURN will display drawing at rotation and scale it was created.
- <O>-old, last drawing selected from disk. Allows alternate rotation and scale.

-
- F7 Erases, copies, animates, moves, smears, or replicates an area
- Mark any two corners of object to be erased or copied with cursor.
- <e>-erases the enclosed area and copies it for use with a,s,r, and m.
- <Alt-e>-erases enclosed area but does not copy it. Use to erase small areas.
- <c>-copies area to be moved, but does not erase
- <C>-copies the portion of the screen to disk for later use. No extension on the
- user supplied name creates a file that can be retrieved with F7 <o>. A .PIC
- extension saves portion of screen for later use and is compatible with
- other graphics programs. A .BAS extension will save the screen as a basic
- subroutine for use in user written programs.
- <Ctrl-c>-copies the same size object as previously copied without remarking.
- <o>-retrieves drawings saved with <C>. A single drive letter will display
- appropriate files on disk.
- <a>-animate allows a previously copied or erased area to be moved around the
- screen with the cursor. As the object is moved vertically off the screen it
- will slowly disappear until the cursor wraps. As the object is moved
- horizontally off the screen it will distort until wrapping occurs.
- <m>,<M>, <Ctrl-m> and <Alt-m>-move area previously erased or copied to lower
- right of cursor, each with a different syntax. (different result)
- <s>,<S>, <Ctrl-s> and <Alt-s>-smear the copied object with each step of the
- cursor using different syntax. Use this as a paint brush. Copied size
- determine number of bristles in brush.
- <r>,<R>, <Ctrl-r> and <Alt-r>-replicates object with each cursor step.
- <n>-returns to CURSOR MODE.
- Note that when a very large or complex object is rotated or zoomed using F1,
- the last copied area maybe lost. It is possible to copy the entire screen. This
- allows two different drawings to be merged.
-
- The last screen copied or erased can be view and further manipulated by
- selecting <Ctrl-End> <Ctrl-PgDn>.
-
- F10 Directory, saves, retrieves an old drawing, starts fresh, or exits.
- <d>-directory of selected disk
- <s>-saves the current drawing - must be room on disk. For best results save
- drawings on B:. Two files will be saved. The first is the screen file
- designated automatically as yourfile.scn. The second is the data file for
- scale information.
- <o>-old-retrieves a stored drawing from disk
- Screens previously created with this program should have an associated data
- file with scale information.
- <t>-template-allows a template screen to be called up. Disables updating of
- disk.
- <f>-fresh-clears screen and starts again. If the current drawing has not been
- saved on disk it will be lost.

- If your printer doesn't support a given pitch answer the corresponding
- prompts for character code and line step with a RETURN.
- <n>-exits function
-
- F4-Prints graphics screen to printer
- <z>-zoom prints partial screen. Enclose area to be printed in box.
- <Z>-Zoom prints entire screen.
- With partial and full screen zoom printing you must specify the characters to
- use and one of three sizes.(1 is the smallest and 3 is the largest)
- <p>-sets up for screen dump or single sheet printing on Okidata 92.
- To print on Okidata select <o> when asked to "Print Screen (y/n)?"
- <n>-exits to cursor mode
- The zoom printing can be set up to work with almost any printer, while the
- single sheet print is currently limited to an Epson (with a screen dump) or an
- Okidata 92.
- help4b
- Print sizes range from 1 to 41
- Size 1 corresponds to 17 cpi
- Size 2 corresponds to 12 cpi
- Size 3 corresponds to 10 cpi
