Date to extract the day from.
FUNCTIONUnder review
Day
Day( <dData> ) --> nDiaExtracts the day of the month from a date.
Overview
Day accepts a date and returns an integer from zero to 31. The reference documents zero for blank or invalid dates. This differs from CDow, which returns the weekday name. The example uses SToD to avoid day/month ambiguity and handles the transition beyond month end. (TOTVS, n.d., ref. 1)
Syntax
Day( <dData> ) --> nDiaParameters
Return value
Integer from 0 to 31 according to the date.

// Adding a day changes the month before day extraction.

ConOut(cValToChar(Day(dReference + 1)))
