Not all the text I am parsing is fixed width, just this bit.
The rest is somewhat like this (deboned to protect client)
document : checkpoint address report(s?) doctrailer
report : report1 | report2 | report3 | ...
report1 : lt[100] report1_cost_centre(s?) lt[200]
report1_cost_centre : lt[300] report1_txn(s?) lt[400]
report1_txn : lt[500] lt[600] page_break(?) lt[700]
lt : "<LT$arg[0]>" lt_data
lt_data : /[^\\]*/ lt_end {$return = $item{__PATTERN1__}
...
but for 15 different reports, hundreds of lt records, lots of options, repeats and alternations.
