new and dispose

Learn new and dispose in Pascal with a construct-specific explanation, unique example, engineering boundary, and mastery check.

10 min read • Intermediate

new and dispose is a focused Pascal topic inside Arrays and Pointers. 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 new and dispose, then change one input and predict the result before running it.

Topic-specific example

pascal Try It Live
var P:^Integer; begin New(P); P^:=8; Dispose(P); end.
Edge case / engineering note

new and dispose 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.
