Section 7. Flexible Format
Max Length
This box allows setting the maximum length limit for the selected MICR field. This choice
creates a variable length field, whose characters are truncated (to the left) only if the actual
length exceeds the maximum length. If the actual length is less than the maximum length, the
characters are not truncated. The input to this box is a decimal number. If the maximum length
is not required, leave the box blank.
Note
The Max length and Fill boxes are mutually exclusive.
If one is selected, the other is not available.
Fill
This box allows setting a fixed or constant length for the selected MICR field. When the Fill
box is checked, three other items become available: Fill length, Fill direction, and Fill
Character. The information in these items is used to “fill” the selected field when the actual
length is less than the fill length.
Fill length
This box is only available when the Fill box is checked (see above). This box contains the fixed
or constant length (number of characters) for the selected field. The input to this box is a
decimal number. A number must be entered in this box.
Fill character
This box is only available when the Fill box is checked (see above). This box allows entering an
ASCII character to fill the selected MICR field when the actual length is less than the fill length.
The space (decimal 32) and zero (decimal 48) characters are commonly used; to fill with either
character, simply click the corresponding button and the Fill character box will automatically
display the corresponding decimal ASCII value. For any other ASCII character, enter the
decimal value in this box (see Display ASCII Table… below).
Fill direction
This box is only available when the Fill box is checked (see above). This box provides the
option of filling the selected field to the left or to the right with the fill character. To select,
simply click the Left or Right button.
