SAS Date creation

[mesfandiari231]

I have a code question to ask you. I will just send it in a moment in teams. I would like to create a couple new variables in a file,
I think (hope) it will be pretty straightforward.

On each record in a data set I have:
Arrival Fiscal Month Arrival
Fiscal YearEncounter Date (formatted mmddyy10.)
On that same record, I want to create two new variables:An "Arrival Date" variable formatted as mmddyy10., where you just set the day to
the first of the month. So if someone has an Arrival Fiscal Month of 07 and an Arrival Fiscal Year of 2021, then their Arrival Date would
be 07/01/21.A flag for whether the Encounter Date occurs within the year prior to the Arrival Date (I assume this will be based on
some sort of datediff function of 365 days or 12 months)

To build a SAS date from separate year/month/day values, use the MDY function.

How?

Read the documentation I linked to.

Or don't you know how functions are used in code?
