FA430FIL

User Function FA430FIL()

Reads the CNAB return line in Model 1.

FA430FILFINA430

01 · OVERVIEW

Overview

The specific page limits usage to Model 1 and documents Nil return. Its table describes the line at position 1, but its sample assigns PARAMIXB directly to cLinha; P12.2210 passes {xBuffer}. Inspect the release caller before indexing or processing this inconsistent context. No useful GitHub implementation was found. (Refs. 1–2)

02 · SYNTAX

Syntax

User Function FA430FIL()

Parameters

Entry point context

UnconfirmedContext to confirm

The complete technical contract remains unconfirmed. Do not assume types, PARAMIXB positions or aliases beyond the evidence described.

Return value

Nil: no return expected on the page.

03 · PRACTICAL EXAMPLE

Editorial example based on documentation

#Include "Protheus.ch"

User Function FA430FIL()
    // Type diagnostic without exposing bank data.
    ConOut("FA430FIL: context type " + ValType(PARAMIXB))
Return Nil

Expected result

Teaching proposal with behavior described in comments. Verify the context before compiling in a test environment. Under review: example not compiled or run in Protheus. Verify aliases, locks, transaction position and compatibility in the target release and patch.

04 · PRACTICAL EXAMPLE

Observed call and context

// P12.2210 caller excerpt (EURAI, ref. 2); not an entry point implementation.
// FINA430.PRX - FA430GER() -> EXECBLOCK("FA430FIL", .F., .F., {XBUFFER})

Expected result

The record shows arguments and immediate return use where present. It omits the full caller body and does not establish commit timing.

BEST PRACTICES

Do not log the complete bank line. Validate bank layout and PARAMIXB shape; do not assume this hook replaces the return buffer.
A call without a fourth argument does not document a PARAMIXB layout. Preserve caller identifiers and do not invent fields or positions.
Test plan: compare standard and customized flows, exercise success, rejection and repetition, and inspect balances, movements and accounting as applicable.
Under review: example not compiled or run in Protheus. Verify aliases, locks, transaction position and compatibility in the target release and patch.
