Make your own plugin! (83)

If you have thought of adding a cool new feature to ZGEO, then make your own
plugin!  Here is a brief list of requirements:

1.      plugin name should begin with GEO. GEOSTD, GEODAY, GEOSAVE, etc.
2.      must be under 2,000 bytes.
3.      send me the program so I can give the stamp of approval.
4.      the first few lines of the program should look like this:

:Output(4,1,"ERROR:  prgmZGEOIS MISSING!
Lbl X (any lable will work.)
prgmZGEO
If Ans=45
Return
put the rest of the plug-in here!
.........
at the end:
Goto X

Information on ZGEO:

        -The variable A determines whether one or 2 functions are on.
        -ZGEO always stores a negative theta to r2.
        -The mode is always set in Radian.
        -Pressing Y= always resets the defaults.
        -Simultaneous graphing is a default setting for ZGEO.
        -to make the program so it does not recall the stored zoom, store
         pi to R.
        
        -The program sets the mode from polar back to function, so your
         plugin may need to change the mode back to polar.

        -ZGEO uses the stored zoom, and Y= changes the values stored to the
         ZOOM

Information on a plug-in:

        ZGEO uses getkey to transfer control from itself to the plug-in. So a
        line in a plug-in may read:

        If Ans=13
        Then
        ClrDraw
        RecallPic 1
        End
        If Ans=15
        pi->R

        Once you press a button and inputed your setting in your plugin, you
        need to loop back to the line that runs prgmZGEO. (see the
        requirements at the top of this document.)

        If you want to, your plugin can be a program that changes the zoom
        stored and the functions, so that it does a really cool design.
