PureBasic is a new "high level" programming language based on established BASIC rules. PureBasic is similar to any other BASIC compiler you may have used, whether for the Amiga or PC. Learning PureBasic is very easy! PureBasic has been created for the beginner and expert alike. Compilation time is really fast. We have put a lot of effort into its realization to produce a fast, reliable and system friendly language.
The syntax is simple but the possibilities are endless with PureBasics advanced features, such as pointers, structures, procedures, dynamically linked lists and much more. The experienced coder will have no problem in gaining access to any of the legal OS structures or API objects.
PureBasic is a portable programming language which currently works on AmigaOS (680x0 and PowerPC), Linux, MacOS X (PowerPC) and Windows computer systems. This means that the same code can be compiled natively the three systems and still use the full power of each. There are no bottlenecks like a virtual machine or a code translator; the generated code produces highly optimized executables regardless of the OS on which it is compiled. The external libraries are mainly written in hand optimized assembler, which produces very fast commands, often much faster than the C/C++ equivalent.
Main features:
- Huge set of internal commands (800+) to quickly and easily build any application or game
- All BASIC keywords are supported
- Very fast compiler which creates highly optimized executables
- No external DLLs, runtime interpreter or anything else required when creating executables
- Procedure support for structured programming with local and global variables
- Access to full OS API for advanced programmers
- Easy but very fast 2D game support trough dedicated libraries (DirectX, SDL, ...)
- Easy and high quality 3D support based on OGRE
- Optimal use of the available hardware by using highly optimized (assembly) commands
- Source code is portable between AmigaOS, Windows, MacOS X and Linux, for games and applications
- Dedicated editor and development environment
- Integrated debugger to easily trace programming bugs.
Technical Features:
- 486, Pentium (Pro, II, III) support
- Built-in arrays, dynamically linked lists, complex structures, pointers and variable definitions
- Supported types: Byte (8 bits), Word (16 bits), Long (32 bits), Float (32 bits) and also user defined types (structures)
- Built-in string types (characters)
- Constants, binary and hexadecimal numbers supported
- Expression reducer (grouping constants and explicit numbers together)
- Standard arithmetic support in respect of sign priority and parenthesis: +, -, /, *, and, or, lsl, asl, lsr, asr
- Very fast compilation (about 300 000 lines/min on a P200)
- Procedure support for structured programming with local and global variables
- All Standard BASIC keywords: If-Else-EndIf, Repeat-Until, etc.
- External library support to manipulate objects like BMP pictures, windows, gadgets, SDL, etc.
- External libraries are fully written in hand optimized assembler for maximum speed and compactness
- The Linux API functions are fully supported as if they were BASIC keywords
Inline assembler
- Precompiled structures with constants files for extra fast compilation
- Configurable CLI compiler
- System friendly, easy to install and use

"Where is M13?" is a revolutionary new astronomy application that helps you visualize the 3-D locations and physical properties of common deep sky objects. This perspective is rarely discussed in the astronomy books and software products on the market, which focus mainly on apparent data such as an objects look, visual magnitude, apparent size, right ascension and declination. "Where is M13?" aims to address this important lack.

Using paired face-on and edge-on views, the Galaxy View shows you where that cluster or nebula you enjoy viewing in your telescope is actually located relative to the center and plane of the Galaxy, providing a unique three-dimensional perspective of the Galaxy.

The Object List provides important physical information about the objects you choose to list. Galactic latitudes and longitudes as well as luminosities, true sizes, and distances are displayed. A quick click of a checkbox brings up a display of the equivalent apparent data.

The Sky View shows you where the objects displayed in the Galaxy View are located in the night sky, using a star map plotted in galactic coordinates. This use of galactic coordinates, rather than the more common equatorial coordinates, helps you really understand the relationship between what you see in the night sky and an objects galactic location.

We think youll find that "Where is M13?" literally adds another dimension to your night sky observing. Enjoy exploring this new perspective!

"Where is M13?" is compatible with Windows, Mac OS X, and Linux.
