Use these positions to specify the decimal placement within a packed decimal, a zoned decimal, a floating point, or a binary field.
Specify a decimal number from 0 through 31 to indicate the number of decimal positions to the right of the decimal point. (This number must not be greater than the number of digits specified in the field length.)
You can override or change these positions if you are using a referenced field. To override the positions, specify the new value. To change the positions, specify the amount by which you want the field increased or decreased and precede it with either a + or -. For example, an entry of +4 indicates there are to be four more digits to the right of the decimal point than were in the referenced field. If the resulting number of decimal positions is greater than the maximum allowed, you will receive an error message.
