Removing date information

[rab24]

I know it sounds strange, but I need to remove information from a date variable going from a variable that includes day of the month to just month. It is part of a deidentification process so a simple format change is not sufficient. Any suggestions on how to permanently restrict my data?

Thanks.

You can try :
1) creating a character variable with the formula PUT(myDate, MMYYS7.) and your new variable will only contain month and year
2) create a new date variable with the formula INTNX("MONTH",myDate,0) and you new variable will be located on the 1st of the month

Thanks Olivier, that works perfectly.

To SAS proper, I'm sure more experienced users probably wouldn't have a problem understanding this, but instead of the syntax intnx( 'month', date, 0) the Enterprise Guide help has the syntax example as intnx( 'month', date, 0, beg )
