SX6 — Parameters

Stores system parameters affecting processing.

SX6 — ParametersAdvPL

01 · OVERVIEW

Overview

SX6 holds system parameters, distinct from SX1 MV_PARxx answers. Value, type, branch and cache refresh affect reads. SuperGetMV documents name, help, default and branch; defaults do not create missing parameters. The teaching block uses a fictional name and logical default without querying the environment. Review changes across all consumers and document rollback. (Sources: refs. 1–2.)

03 · PRACTICAL EXAMPLE

Commented example

#Include "Protheus.ch"

User Function Ed685()
    // Fictional name; a logical default does not create an SX6 record.
    Local bParameter := {|| SuperGetMV("MV_X_ED685",.F.,.F.)}
    ConOut(ValType(bParameter))
Return Nil

Expected result

Creates block B without reading or modifying the parameter. Under review: editorial example neither compiled nor run in Protheus. Check includes, release, RDD and context before testing.

BEST PRACTICES

Keep default types consistent; do not log sensitive parameters. Confirm branch and cache-refresh policy.
