Server Utilities :: SQL Loader With WHEN And DISCARD?

My data file contains records with RECORD_TYPE '01', '02', '03' and '04' in position (30:31) I use sql loader to load this data into a table. I need to load ONLY rows with RECORD_TYPE ='04'. I have to output all the other rows into a file, so I decided to use DISCARD file. Now, those with RECORD_TYPE ='4' have to be loaded into different columns depending on the value in position (267:268).

So, my ctl file should look something like:

WHEN (30:31) = '04'
into table MYDATA
WHEN (267:268) != 'O '
into table MYDATA
WHEN (267:268) = 'O '

and whatever is not '04' goes to discard file.

I tried to use

into table MYDATA
WHEN (30:31) = '04' and (267:268) != 'O '
into table MYDATA
WHEN (30:31) = '04' and (267:268) = 'O '

but I don't get the right result in terms of the discard file.

Is there any way to put together all these conditions?
