In [[Perl]], the [[keyword]] "<code>use</code>" can introduce a "pragma", such as <code>use strict;</code> or <code>use utf8;</code>.

In [[Visual Basic]], the statement "<code>Option Explicit On</code>" instructs the VB compiler to require all variable declarations before use. There are also a few other variations to the <code>Option</code> keyword, such as:

* <code>Option Strict On</code> - Requires that implicit type casts are only to wider types.

* <code>Option Compare Binary</code> - Tells the compiler to compare text using a binary algorithm.

* <code>Option Compare Text</code> - Tells the compiler to compare text using a textual algorithm.
