How to add a date condition to for each loop in Progress 4GL query?

I have difficulties with a query I have to change to limit the data I export from a Progress database. I export "myorderdate" to a text file. However, I have to limit the data to only orders after year 2012.

OUTPUT STREAM s1 TO VALUE(exportFileStringDirectory).
FOR EACH poTable NO-LOCK WHERE
ponum = 1 AND
/* this doesn't work -->*/
/*myorderdate.YEAR >= DATE("2012").YEAR AND*/
conum = 1:

PUT STREAM s1 UNFORMATTED
ISO-DATE(myorderdate)
