program header
Learn program header in Pascal with a construct-specific explanation, unique example, engineering boundary, and mastery check.
program header is a focused Pascal topic inside Program Basics. This lesson explains the construct itself, the state or value it operates on, and the observable result it produces.
Read the example as a small executable experiment. Identify the exact syntax that belongs to program header, then change one input and predict the result before running it.
Topic-specific example
program Demo; begin writeln('ready'); end.
program header has rules that are easy to miss when the example is copied mechanically. Check the feature-specific boundary shown by this construct: scope, mutability, evaluation order, type constraints, lifetime, error behavior, compile-time restrictions, or resource cleanup where applicable.
