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
its
between 1975 and 1985. How would you accomplish this in
data step code? Using only PROC FORMAT.

Here is the correction in above example,
proc format;
value datestyl low-'31dec1974'd = [date7.]
'01jan1975'd - '31dec1985'd = 'disco Years'
'01jan1986'd - high = [date9.] ;
Run;
Example:
data k1;
input date2 $9.;
cards;
31dec1974
01jan1975
01jan1985
01jan1990
;
data temp;
set k1;
date1=input(date2,date9.);
sam = date1;
format sam datestyl.;
run;
proc print;
run;
