Create a new variable whose value is a month name. Note: If your numeric is a SAS date value (the number of days since January 1, 1960) you can use the MONNAMEw. format to either display the SAS date as its month name or create a new variable using the PUT function. See Sample 1. If you have a numeric with values 1-12, you'll need a user-defined format. See Sample 2.
Public Function MonthName( _ ByVal Month As Integer, _ Optional ByVal Abbreviate As Boolean = False _ ) As String. Required. Integer. The numeric designation of the month, from 1 through 13; 1 indicates January and 12 indicates December. You can use the value 13 with a 13-month calendar. If your system is using a 12-month calendar and Month is 13, MonthName returns an empty string. Optional. Boolean value that indicates if the month name is to be abbreviated. If omitted, the default is False, which means the month name is not abbreviated.
