I haven't attempted a grammar yet but below is a textual example:
The file should contain three fields called "jobNo", "description" and "cost".
The fields should adhere to the following specifications (regex in braces):
jobNo: must be digits only, maximum 5 - (\d{1,5})
description: any lowercase characters or space upto a maximum of 128 - ([a-z
]{1,128})
cost: positive or negative amount formatted as upto 5 digits before the
decimal and 4 afterwards zero padded - (-?\d?\d?\d?\d?\d\.\d\d\d\d)
E.g.
"jobNo","description","cost"
"12345","this record conforms","123.4321"
"987","this RECORD does not conform because of uppercase usage","-22.44"

Hi Phil,
could you provide a textual definition of your grammar, and/or your ANTLR
specification so far?
Cheers,
Nick
