Format:

LEN,Min,Max,

Length field consists of two length parameters: minimum length (Min)
and maximum length (Max). When defined, a formula will be
performed if the length of the original data falls between MIN and
MAX

When missing, the following fields of current Formula are always
processed.
Example:

LEN,9,48,

means the length of original data must be within 9 and 48.

Format:

MATCH, P0 ,"C0" ,P1, "C1" ,...,Pn, "Cn" ,

a pair of Pn and Cn forms a Match field (n indicates a sequential
integer number).  To define a Match field, two parameters are required.
The first is character position (Pn) and the second is a string (Cn).
Character position means the number of characters, counting from the
first character to the one to be positioned in the data record.
For example, in the following data

BARCODE

'B' has position 1.
'A' has position 2.
...
'E' has position 7.

When Match field is defined, the original data string starts at the
position specified by the first parameter P and will be compared with
string "C". If the match is identical, processing of current Formula
continues.
The position parameter P could be a wild character * for any position
or # for the last position in the original data. If # is used,

#-N

is valid.  Here N is a digit parameter.
The string parameter C can include * for any digit or # for any letter.
Examples:

MATCH,3,"AB",#,"?",
