What numeric value to expect from FA09, AA20 or AS34? The first two could be considered HEX which SAS can read but the last not. If you want to get rid of the letters before the conversion then

new_a = input(compress(a,'A',' '),4.);

might work which says to replace all alphabetic characters, 'A' code, with spaces ' '
