EXIT terminates the execution of a block of code in a Do...Loop, For...Next, For Each...Next, Function, or Sub. When used to exit a loop, either Do...Loop, For...Next, or For Each...Next, execution continues with the first statement after the loop; if the loop is nested inside another loop, control is transferred to the loop outside the loop where the EXIT is encountered. When used to exit a Function or Sub procedure, execution continues with the first statement after the statement which called the procedure.

Description

Exit terminates the execution of a block of code in a Do...Loop, For...Next, For Each...Next, Function, or Sub. When used to exit a loop, either Do...Loop, For...Next, or For Each...Next, execution continues with the first statement after the loop; if the loop is nested inside another loop, control is transferred to the loop outside the loop where the Exit is encountered. When used to exit a Function or Sub procedure, execution continues with the first statement after the statement which called the procedure.

Example

'Exit terminates loops and procedures
Dim i
For i = 1 to 10
