01 · OVERVIEW

Overview

The historical Protheus 10/11 page receives buttons in PARAMIXB[1] and returns the edited array. Its sample removes position five, which is not a stable action identifier across releases. P12.2210 assigns the result to aRetorno in MenuDef. No useful GitHub implementation was found. (Refs. 1–2)

02 · SYNTAX

Syntax

User Function FA330LIB()

Parameters

PARAMIXB[1]

ArrayExecution context

Screen buttons received. (Refs. 1–2)

Return value

Array of buttons to be used by the routine.

03 · PRACTICAL EXAMPLE

Editorial example based on documentation

#Include "Protheus.ch"

User Function FA330LIB()
    // Preserve received actions; do not remove fixed positions.
    Local aButtons := AClone(PARAMIXB[1])
Return aButtons

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.
// FINA330.PRX - MENUDEF() -> ARETORNO := EXECBLOCK("FA330LIB",.F.,.F.,{AROTINA})

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

Resolve actions against the target release menu. Hiding a button does not replace processing authorization. The sample below preserves all buttons.
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.
