MagTek Device Drivers for Windows

A format rule describes how the data is to be parsed. Characters that must be matched as literals are placed as is in the string or preceded with a ‘\’ if the character is one of the following: ‘[’, ‘]’, ‘(’, ‘)’, ‘*’, ‘_’, ‘<’, ‘>’, ‘:’, ‘.’, or ‘\’. Fields that are either to be parsed or ignored are contained within <>. The format rules string cannot exceed 1027 characters. The following is an example for retrieving the customer name and account number from track 1:

{%B<acct_no>^<cust_name>^<*>?}

The ‘%’ specifies the start sentinel and ‘B’ specifies a format ID for the track. These two characters must be matched for the remainder of the rule to be executed. <acct_no> specifies that all data up to the following ‘^’ should be stored in a property named “acct_no”. <cust_name> specifies that all data up to ‘^’ should be stored in a property named “cust_name”. <*> specifies that the remainder of the track data up to ‘?’ should be ignored.

The following table describes the procedure for specifying fields. Remember that property names can have a maximum of 11 characters.

Note

If there is a property specified more than once in a rule, the last successful match will be saved in the property. The driver will ignore previous matches and the value will not be compared to the previously saved value for consistency.

Field Type	Example	Description
Variable size field	<acct_no>	All data up to the next field separator or
		end sentinel is stored in a property named
		“acct_no”.
Fixed size field	<exp_date[n]>	Store the next n characters in a property
		named “exp_date”.
Variable size field	<cust_name[x..y]>	Store at least x characters and at most y
with limit		characters up to the next field separator or
		end sentinel into property named
		“cust_name”.
Variable size	<*>	Ignore all characters up to the next
(ignore)		character specified in the format string
		(usually a field separator) or the end
		sentinel character (?).
Fixed size (ignore)	<*[n]>	Ignore the next n bytes.
Variable size with	<*[x..y]>	Ignore at least x characters and at most y
limit (ignore)		characters up to the next literal found.
