I need to setup a LF that has multiple COMP designations and I am not quite 
sure how to position it within the SEU.

What I need to do is a date range for 02/01/2005 through 01/31/2006

I thought I could do something like

     A          S IHDINVDATE                COMP(GT '02/01/2005' AND LT
     A                                      '01/31/2006')              


But that doesn't work.

Suggestions? All of the manuals I have do not give examples or instructions 
on making multiple comparison statements within the dds.

I'm a bit rusty on this, but wouldn't you just do:
     A          S IHDINVDATE                COMP(GT '02/01/2005')
     A            IHDINVDATE                COMP(LT '01/31/2006') 

AFAIK, the above is an 'AND' condition, and if you had prefixed the second
'IHDINVDATE'
with 'S', then it would have been an 'OR'. Each 'S' in column 17 starts a
new, and unrelated select group. You might need to add an omit group
afterwards as well, like:
     A          O                           ALL                        

You should double-check the DDS Reference Manual though, I'm positive it has
plenty of examples and explanations of this in the logical file section.
