Typically cupa_dt is greater than start_dt. However, when start_dt is greater than cupa_dt I need to switch around start_dt and cupa_dt to get the correct difference between the two dates. Is there any way to accomplish this without creating a flag (ie cc_check)?
cupa_dt=dhms(TDT,0,0,TTM);
start_dt=dhms(CSDAT,0,0,CSTIM);
cc_check=0;
if (start_dt>cupa_dt and cupa_dt ne .) then cc_check=1;
if(cc_check=0) then do;
cc_diff=round(((cupa_dt-start_dt)/86400),0.01);
end;
if(cc_check=1) then do;
cc_diff=round(((start_dt-cupa_dt)/86400),0.01);
end;
Thank you.
Just add abs function
cc_diff=round(((abs(cupa_dt-start_dt))/86400),0.01);
although you have one solution, here is another
difference = range( date1, date2 ) ;
Here is some code to demo the result .
data ;
do date1 = today() - 3 to today()+2, . ;
do date2 = today() - 3 to today()+2, . ;
diff= range( date1,date2) ;
output ;
end; end;
stop;
format date: date. ;
run ;
