I have a string parameter that I have that I enter as a date (mm/dd/yyyy). I do not have this parameter enclosed in quotes because of something I am doing later in the process. I then want to subtract 1 day from this date that is being entered. So, I am trying to convert this string into a date so I can use the INTNX function. I am having troubles converting the parameter string into a date format.
Try using the INPUT function in a SAS variable assignment statement, specifying the appropriate INFORMAT name as the second argument. Check resources on the SAS support http://support.sas.com/ website, such as the technical conference paper listed below.
