Interpret bank checks

The fact that FORMS can interpret specific typefaces makes it suited to processing bank checks.

When you create a form definition to use for processing checks, follow these special steps:

For the line of numbers and symbols usually found at the bottom of checks (the Magnetic Ink Character Recognition or MICR line), specify a specific typeface in the character field to be interpreted.

The MICR line has different typefaces in different countries. For example, E-13B is used in the United States and United Kingdom, and CMC-7 is used in France. OCR-A and OCR-B are also used.

Since special characters are likely to be a part of what is captured, select Special characters on the Standard tab of the Field dialog.
Include special characters in the format specification.

FORMS can interpret the control symbols separating different parts of the MICR line. These characters appear in the output as follows:

Symbol	FORMS representation
$images\bank_control_chars1.gif$	# (hash mark)
$images\bank_control_chars2.gif$	- (dash)
$images\bank_control_chars3.gif$	@ (at sign)

The symbols and numbers often appear in a fixed format (the same number of digits, and always in the same position). Therefore, creating a more rigid format specification could result in better interpretation. For example:

Source format: $images\bank_control_chars4.gif$

Possible format specification: X[#]N(8)X[@]

Include the special characters (especially # and @) in the character set that FORMS is using. How?
