Infile - This is an input file, tab delimited, and containing source data.

Ffile - This file contains field # and the filter to use on it.
This is a tab delimited file with the field # (Starting with 1)
and the name of the filter to apply to that field.(e.g. UPPERCASE 1).
Some filters will themselves have further arguments.
(e.g. SUBSTITUTE # oldstring newstring CASE|NOCASE)
Some filters, like NAME, will divide a field into several fields (e.g. salutation, first, middle, last, suffix, gender, ethnicity)or like CSZ, (e.g. city, state, zip5, zip4, zip2)
A wide variety of filters will be developed as time and need permits.

CURRENT FILTERS INCLUDE:

* LOWERCASE field
* UPPERCASE field
* CAPITALIZE field
* SWAP field1 field2
Exchanges the contents of field1 and field2.

* CHARACTERFIX field fname
The file contains lines, each containing 2 characters.
The first character is the search char,
the second is the replacement char.

e.g. Aa, Bb

This can be used to convert extended roman characters to
the nearest regular letters.

* REPLACE field findstring replacestring
Finds all occurances of the findstring in the specified field and replaces it with the replacestring. Searches are NOT case sensitive.

* SPLIT field column
Splits a field after column selected.
e.g. 3 leaves 3 characters in first half.

* TELEPHONE field

This standardizes telephone numbers.
This does not work for international numbers.
Spelled phone numbers are converted to numeric
numbers

* CSZ

The CSZ filter corrects spelling, format and case. This should improve the address correction percentage. The data file for the city lookup is a text file that can be easily updated as needed. Misspellings and case can be corrected by entries in that file. There are thirteen thousand entries in that file.

* VFCFIX field len "vfc1" "vfc2" "vfc3" "vfc4" "vfc5"

This converts aberrant VFC format codes that are sometime encountered. Most VFC formats can be fixed with this filter. Usually a VFC format file can be treated as a 1 field tab delimited file. Each line can be read as a single field and the VFC codes fixed to be handled as a normal VFC file and converted using JT-convert.

field is the field number to fix, normally 1.

len is the length of the VFC code, usually 1, but I have seen 4.

vfc1 is the string that indicates a new page.
vfc2 is the string that indicates an overprint. (Usually ignored)
vfc3 is the string that indicates Skip 1 line and Print (i.e. next line)
vfc4 is the string that indicates Skip 2 lines and Print
vfc5 is the string that indicates Skip 3 lines and Print
Any other string will be ignored and changed to a "skip 1 line and print"

Thank you, Cody, for your assistance in this peculiar problem.

Outfile - This is an output file, tab delimited, containing the filtered data.
