Overview

AdvPL Fundamentals (Grade A) is a security-tested development skill for Claude AI. It focuses on fundamentals of ADVPL/TLPP, including Hungarian notation, naming convention, local and global scopes, and name length limits. ADVPL (Advanced Protheus Language) and its successor TLPP are proprietary languages derived from Clipper/xBase. They have strong conventions that are not optional in high-quality Protheus code. This skill is essential for Protheus developers, especially when creating or refactoring variables and functions. The skill addresses common pitfalls, such as the silent bug in ADVPL classic, where a variable's name truncates to 10 characters, and the importance of using the correct scope for variables. It covers when to use local, static, private, and public variables, including rules of thumb for their visibility and lifetime. The skill is designed to be a practical guide for developers to avoid common mistakes and improve their ADVPL/TLPP coding skills.
