1) Insert an END statement between the last control record and the first data record,
2) Insert an END statement after the last data record.
3) Make sure the FORMAT statement does NOT contain any lower case x characters (use upper case X)
So, the input should look something lik this:
TITLE=MODEL A EXPECTED VALUE DATA W/ PHI=.6; P=.5; N=1000,B=200 PERIODS=4 FORMAT=(4I1,I4) 1111 13 1110 41 1101 13 1100 101 1011 13 1010 41 1001 13 1000 301 0111 22 0110 62 0101 22 0100 162 0011 52 0010 132 0001 152
