There is a field containing a date. It needs to be
displayed in the format
"ddmonyy" if it's before 1975,
"dd mon ccyy" if it's after 1985, and
as 'Disco Years' if it's between 1975 and 1985.
How would you accomplish this in data step code? Using
only PROC FORMAT

Answer / amit gupta
Apologies,
above code has an extra "FROM d1"
The working code is as below:
proc sql;
select
case when date lt '31DEC2006'd then date end as mydate
format=date7. ,
case when date gt '31DEC2008'd then date end as mydate
format=date9. ,
case when '01JAN2007'd <= date <= '31DEC2008'd then 'DUMMY'
end as mydate
from d1 ;
quit;
However it does give the data in 3 columns , which I was
unable to merge as the data type was different.
Any working solution using format ?

Answer / amit gupta
proc sql;
select
case when date lt '31DEC2006'd then date end as mydate
format=date7. from d1
case when date gt '31DEC2008'd then date end as mydate
format=date9. ,
case when '01JAN2007'd <= date <= '31DEC2008'd then 'DUMMY'
end as mydate
from d1 ;
quit;
Just that these are in three different columns;
Tried the above resolutions but unsuccessfully.
