datalines;

101 1 4 hr

101 2 8 hr

101 3 12 hr

101 4 16 hr

run;

data t2_1;

set t2;

by subjid;

retain cnt  0;

if first.subjid then cnt = 0;

cnt+1;

if cnt ~= rowno then output  t2_1;

Another thought:

Where order is defined by a numeric var, use the DIF() function like :

Data ordered unordered ;

Set your.data ;

by subjID ;

drop difff ;

Difff = dif( rowno ) ;

if first.subjid then output ordered ;

Else  if difff GE 0 then output ordered ;

else output unordered ;

Run ;
