HI, ALL
I want to get the last value in each group with define field.
and in car file we use car and model field.
define a field TTmodel = ''||' OR '||MODEL||''''

so we can get a string like OR 'V12XKE AUTO' OR 'XJ12L AUTO' etc.

the question is how can I get the TTMODEL string by group car.

infact i need the result like
CAR TTMODEL
JAGUAR OR 'V12XKE AUTO' OR 'XJ12L AUTO'
JENSEN OR 'INTERCEPTOR III'
DATSUN OR 'B210 2 DOOR AUTO'
……

I use the follow script and get the Wrong result

DEFINE FILE CAR
TTMODEL/A500V=TTMODEL || ' OR ''' || MODEL || '''';
END
TABLE FILE CAR
PRINT
'CAR.COMP.CAR'
'CAR.CARREC.MODEL'
'CAR.CARREC.TTMODEL'

ON TABLE PCHOLD FORMAT HTML

END


so anybody can help me ?

thank you all

LAST function will help to get this. Before using LAST function, records need to be sorted on that field.

TABLE FILE CAR
BY CAR
BY MODEL
ON TABLE HOLD AS HLD_SORT 
END

DEFINE FILE HLD_SORT
TTMODEL/A500V=IF CAR EQ LAST CAR THEN TTMODEL | ' OR ''' || MODEL || '''' ELSE MODEL;
END
TABLE FILE HLD_SORT
PRINT 
MODEL
TTMODEL
BY CAR
END

Hope this helps.

thanks Ram

the follow is the right code


TABLE FILE CAR
BY CAR
BY MODEL
ON TABLE HOLD AS HLD_SORT
END

DEFINE FILE HLD_SORT
TTMODEL/A500V=IF CAR EQ LAST CAR THEN TTMODEL | ' OR ''' || MODEL || '''' ELSE MODEL;
END
TABLE FILE HLD_SORT
SUM
LST.TTMODEL
BY CAR
END
