01 · OVERVIEW

Overview

EXIT leaves WHILE/ENDDO or FOR/NEXT before normal completion. The function continues after the loop: it differs from RETURN and transactional BREAK. Here the condition precedes summation; when the counter reaches three, the sum remains 1+2. Statement order expresses the rule rather than mere formatting. (TOTVS, n.d., ref. 1)

#Include "Protheus.ch"
User Function Ed375()

    Local nSum := 0
    For nIndex := 1 To 5
        // Exit before including the first out-of-scope value.
        If nIndex == 3
            Exit
        EndIf
        nSum += nIndex
    Next nIndex
Return nSum
