[9fans] 3 PQ questions

[Petr Cejchan]

Hi,

I'm new to pq IRDBS thus I've got these stupid questions:

i)   can I match all records with field value less than (greater
than) a specified value? '<' and '<' don't work for obvious
reasons...

ii)  is this a correct implementation of a relation from multiple
fields in A to a single field in B: 

A:                       B:
...                      COLOUR
COLOURFROM               COLOURFROM
COLOURTO                 COLOURTO
COLOURMID                COLOURMID
...

and give COLOURFROM, COLOURTO, and COLOURMID the same code in B?

iii) what does the '+' sign in dispatch file exactly mean? I
found that when omitted the relation doesn't establish...so I use
it without knowing what I'm doing.

Thanks,
regards,
++pac.
