<paragraph xml-lang="en-US" role="paragraph" id="par_id3151211">When a program encounters a <literal>While</literal> statement, it tests the condition. If the condition is <literal>False</literal>, the program continues directly following the <literal>Wend</literal> statement. If the condition is <literal>True</literal>, the loop is executed until the program finds <literal>Wend</literal> and then jumps back to the <emph>While</emph> statement. If the condition is still <literal>True</literal>, the loop is executed again.</paragraph>

<paragraph xml-lang="en-US" id="par_id3151041" role="paragraph">Unlike the <link href="text/sbasic/shared/03090201.xhp" name="Do...Loop">Do...Loop</link> statement, you cannot cancel a <emph>While...Wend</emph> loop with <link href="text/sbasic/shared/03090412.xhp" name="Exit">Exit</link>. Never exit a <literal>While...Wend</literal> loop with <link href="text/sbasic/shared/03090302.xhp" name="GoTo">GoTo</link>, since this can cause a run-time error.</paragraph>
