Raptor is a Windows development platform oriented toward students, scientists and software engineers. It is possible to use flowcharts to express a wide variety of algorithms.

Programming rules

The included language contains the following types of names:

variables;
subcharts;
procedures;
and functions.

All names begin with a letter. Spaces are not allowed and operators are not case sensitive. There are six main symbols for constructing flowcharts: assignment, call, input, output, selection and loop.

You can view common use examples in the included documentation. The Watch section provides feedback on the values of all arrays during the flowchart execution.

Variables

This software offers users a wide variety of math operators and trigonometric functions. Like in Flowol, it is possible to insert boolean expressions into the flowchart and perform string comparisons.

The structure of any variable has to contain only indexed names. This platform supports both one-dimensional and two-dimensional arrays.

RaptorGraph

There is a module for outputting images to a separate window. You can draw geometrical shapes in different colors by programming the coordinates and RGB values for every pixel.
