MarkBrow
MarkBrow(cAlias,cCampo,[cCpo],[aCampos],[lInverte],cMarca,[cCtrlM],[uPar],[cExpIni],[cExpFim],[cAval]) -> NILDisplays a legacy mark-selection browse.
Overview
Alias, mark-storage field and cMarca form the minimum contract. aCampos defines columns; callbacks and ranges depend on the index and caller. Requires Private cCadastro and aRotina. A mark is not a business permission or authorization to change records. This example prepares a reduced call without opening a window or writing real tables. Historical reference: verify behavior in the deployed release/RDD. (Sources: refs. 1–2.)
