Oracle SQL*Loader WHEN Clause Raising Error 2 - oracle

Question

I am trying to exclude the last line of a data file using SQL*Loader, using the WHEN clause, but when it gets to that line it populates both the bad and discard file, and raises an Error 2.
The line to ignore is the last line and starts with "NOL".
After some reading, Error 2 is a warning about the synatx of the CTL file, but cannot find out where it is wrong. Note, if l remove the last line and then run the SAME CTL file, no ERROR is raised, so the issue cannot be the synatx of the CTL file.
To resolve the issue, l am removing the last line BEFORE loading the data, but would like to find out what the issue is for any future use of the WHEN clause.
I have tried:
file_dt != 'NOL'
(1:1) != 'N'
. . .
But l get the same Error 2.
Has anybody else come across this issue? Or have something that l can try?

I'm not on Unix. Nonetheless, loading should work the same.
Table:
SQL> desc test
Name Null? Type
----------------------------------------------------- -------- --------------------------
FILE_DT DATE
A_NUMBER NUMBER
SQL>
Control file (I included sample data into it, for simplicity):
OPTIONS (READSIZE=51200001, BINDSIZE=51200000, ROWS=5000, ERRORS=0, SKIP=1)
load data
infile *
replace
into table test
WHEN (01) <> 'NOL'
fields terminated by ','
trailing nullcols
(
file_dt DATE "YYYY-MM-DD",
a_number
)

Seems to be OK.
So, what did I do differently?
modified WHEN clause
fields are terminated by comma, not semi-colon
removed superfluous information
