01 · OVERVIEW

Overview

The official catalog offers no complete page. P12.2210 shows lF590COK .And. !(ExecBlock(...)), with {"P",cNumBor} or {"R",cNumBor}. The result is negated in the condition, but its branch body was not recovered: this cannot establish whether .T. permits or blocks cancellation. No useful GitHub example was located. (Refs. 1–2) Research includes indexed TDN evidence; no complete specific page was recovered.

03 · PRACTICAL EXAMPLE

Observed call and context

// P12.2210 caller excerpt (EURAI, ref. 2); not an entry point implementation.
// FINA590.PRX - FA590CANC() -> IF LF590COK .AND. !(EXECBLOCK("F590COK",.F.,.F.,{"P",CNUMBOR}))
// FINA590.PRX - FA590CANC() -> IF LF590COK .AND. !(EXECBLOCK("F590COK",.F.,.F.,{"R",CNUMBOR}))

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

Recover the entire conditional block before selecting a return. A constant-return function can reverse the intended decision.
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.
