A Brief Introduction

Welcome to Sheerpower Programming

Sheerpower is a programming language designed for business applications. It offers fast compilation, accurate math (16 decimal digits of guaranteed accuracy), and a simple syntax. Developers can build scalable, efficient programs for handling large volumes of data.

This tutorial introduces key features of Sheerpower, such as high-precision math, fast compiling, dynamic data clustering, and a built-in web server.

Note for Beginners: Sheerpower handles complex systems like memory management and stack control automatically. You don’t need to understand how features like the Chunked FDA or its stackless virtual machine work to use the language effectively. These advanced technologies run seamlessly in the background, so you can stay focused on writing clean, high-performance business code.

Examples

Program Declaration

Every Sheerpower program may begin with an optional PROGRAM statement, which assigns a program name used in crash reports, profiling, and other system-generated files.

program hello_world print "Hello World" end

Stopping the Program

Use STOP or END to end a Sheerpower program. Both are optional. They close open files, flush buffers, unlock resources, and stop execution.

END also marks the logical end of the source file. If it’s missing, Sheerpower automatically inserts it at the end of your code.

Optimized Decimal-Precise Arithmetic

Sheerpower’s REAL data type guarantees exact decimal results with no rounding errors. Internally, it stores numbers as two 64-bit integers— one for the integer part (up to 18 digits) and one for the fractional part (up to 16 digits). This design provides precision critical for business and financial applications, where small errors can lead to significant issues. By using integer-based operations for addition, subtraction, and multiplication, Sheerpower achieves high performance compared to traditional decimal arithmetic.

For example, adding 0.1 and 0.2 in Sheerpower yields exactly 0.3, avoiding the floating-point inaccuracies common in other languages. This eliminates the need for tolerance-based comparisons often required to handle binary floating-point imprecision.

print (0.1 + 0.2) - 0.3 // Outputs exactly 0.0

This ensures reliable calculations for applications like financial software.

Sub-Second Compilation

Sheerpower compiles at over 500,000 source lines per second on a modern PC — meaning even large business applications compile within a second or two. For example, a build of 872,133 lines (with 419 include files) compiled in under 2 seconds on a $1200 mini-server. This speed virtually eliminates the compile–wait–test cycle that slows development in other languages.


High-Performance Data Clusters

Sheerpower's cluster feature works like an in-memory spreadsheet, processing hundreds of thousands to millions of rows per second depending on data complexity and available system resources.

Note: Cluster arrays can handle extremely large datasets (tested with hundreds of millions of rows) with fast key lookups, limited primarily by available RAM.

Comprehensive Statistics Package

Sheerpower includes a built-in statistics package with over 30 functions for analyzing data. These functions can be used to identify trends, variability, and relationships in large datasets. Applications include finance, manufacturing, science, and more. For details, see Sheerpower Statistics .

Web Server Integration

Sheerpower includes a built-in web server optimized for memory-to-memory data transfers. This enables very fast web-based transactions with minimal resource usage. For more details, see the tutorials on Sheerpower Internet Services (SPINS) , Browser Scripting , and Fast-CGI for RESTful Endpoints .


Summary

Sheerpower is designed for business applications, with a focus on speed, precision, and long-term reliability. It is not intended for system-level programming or memory-limited environments. Key features include:

  1. High-Precision Math: Ensures accuracy for financial and data-focused applications.
  2. High-Speed Compilation: Enables fast development and quick testing cycles.
  3. Clusters for Data Processing: Handles large datasets efficiently.
  4. Smart Parameters: Routines automatically adapt to different data types, reducing code complexity while maintaining safety and performance.
  5. Local Routines: Encourages modular code and easier maintenance.
  6. Integrated Web Server: Supports many transactions per second with low resource use.
  7. Backward Compatibility: Ensures continuity and reduces maintenance costs.
  8. Secure Deployment: Protects source code from prying eyes and enables secure, fast, portable distribution — ideal for commercial software.
  9. Reliability: Eliminates common failure modes like stack overflows and unpredictable performance pauses, ensuring stable operation under load.

In Conclusion:

Sheerpower empowers developers to build fast, accurate, and scalable business software. It excels at applications that process large data volumes and demand reliable performance.
