Code:

Code:

ale,AAM,id2_1_2_1_1,23,2013-01-30,1,1
ale,BAND,id2_1_1_1_1,31,2013-01-28,1,1
ale,CAI,id2_1_1_1_1,23,2013-01-28,1,1
ale,CAI,id2_1_1_1_4,23,2013-01-28,1,1
ale,CAI,id2_1_2_1_1,23,2013-01-30,2,1
ale,NAST,id2_1_1_1_1,23,2013-01-29,1,1
ale,NAST,id2_1_1_1_1,31,2013-01-29,1,1
ale,NST,id2_1_2_1_1,31,2013-01-28,1,1
ale,PAB,id2_1_1_1_1,31,2013-01-30,2,2
ale,PAB,id2_1_2_2_3,23,2013-01-28,1,1
