User-defined edit codes 5 – 9

  1. The X edit code ensures a hexadecimal F sign for positive values. Because the system does this for you, normally you do not have to specify this code.
  2. The Y edit code suppresses the leftmost zeros of date fields, up to, but not including the digit preceding the first separator. The Y edit code inserts slashes (/) between the month, day, and year according to the following pattern (with zero suppression):
  3. nn/n nn/nn nn/nn/n nn/nn/nn nnn/nn/nn nn/nn/nnnn nnn/nn/nnnn nnnn/nn/nn nnnnn/nn/nn
  4. The Z edit code removed the sign (plus or minus) from a numeric field and suppresses leading zeros.
