\fs18\cf1 is the strongest feature of Formula Graphics.
\par It has five animation formats and four playback modes. An animation can be played transparently over any background. Palette management automatically allocates colors and remaps animation frames on the fly.
Formula Graphics Multimedia System can be used to produce any type of multimedia presentation. Presentations can be 256 color, 16 bit or 24 bit color. Using simple techniques, very high levels of interactivity can be achieved.

\par The}{\fs16\cf1 Formula Graphics programming language }{\fs16 is similar to other programming languages like BASIC and C. A wide variety of in
structions are available and each instruction performs some particular operation. A program can be written using a list of instruction statements. Only one instruction can be written on each line. The instructions will be executed one at a time in the ord
er they are listed. After the last instruction has been executed, the program will end.
