IndRegua
IndRegua(cAlias,cIndice,cExpress,[xOrdem],[cFor],[cMens],[lExibir])Creates a filtered temporary index in the historical model.
Overview
The manual describes alias, index file, expression, optional order, filter, message and display flag. xOrder D indicates descending. This historical contract depends on the RDD and is not permanent SQL index creation. The example only prepares a block for an alias and exclusive test index name. (Sources: refs. 1–1.)
