I have a very short data lines program and am using truncover, but I get an error that subject and ipred is missing.  Can anyone tell me why subject and ipred are missing?   All of the data are numeric.

Your code worked fine when i tested

data sampled;
infile datalines truncover;
input trtgrp subject time ipred ;
datalines;
1 1 0 0
;
run;

proc print noobs;run;

Log:

832 data sampled;
833 infile datalines truncover;
834 input trtgrp subject time ipred ;
835 datalines;

NOTE: The data set WORK.SAMPLED has 1 observations and 4 variables.

SAS Output

trtgrp	subject	time	ipred
1	1	0	0

I think that for some reason the code was in an area that I had commented.  When I moved the code it did work ok.
