Logical File Select keyword question

Hello all,

I am having one of those Monday morning where I can't seem to remember
S*&%. It could be old age. LOL
I know that there is a way to great a logical file and select out a
range, values or comp for data in a field. I also that you can string
Select statements to great an AND condition. BUT what I cannot remember
is how to do an OR select.

I have a file where I am already doing a select:
A S I$DCTO COMP(EQ 'W')
A IODCTO COMP(NE 'WR')

I need to add another select for an OR statement that would be:
A S IOLITM COMP(EQ 'GDT')
A IODCTO COMP(NE 'OP')

The above gives me the effect that looks like is it all AND's.
Does anyone know how to do this? What I am not seeing or using.

TIA,
Jim
