Please, How do I fix this;

proc iml;

use Complete;

read all var _all_ into DM;

close;

frequency =DM[,5]; y =DM[,4]; status=DM[,3]; Censored= DM[,2]; time = DM[,1];

use GIB;

read all var _all_ into Col;

timeS=time;

locC=loc(censored=1); matrix=J(1,6,-99);

do im=1 to 25;

do j= 1 to frequency[1];

A=RANUNI(-1);

i=max(loc(Col[,j]-A>0));

timeS[locC] = time+ (time[i+1]-time)*((Col[i,j]-A)/(Col[i,j]+col[i+1,j]));

end; sim=repeat(im,nrow(time),1);

temp=status||censored||time||Y||timeS||sim;

Matrix=matrix//temp;

end; matrix=matrix[2:nrow(matrix),];

create impute_t var{status censored time Y timeS sim};

append from matrix;

quit;

843 proc iml;

From your error message, in the statement;

857 timeS[locC] = time+ (time[i+1]-time)*((Col[i,j]-A)/(Col[i,j]+col[i+1,j]));

the subscript in time[i+1] exceeds the dimension of time vector. This would happend if col[i,j] > A for some i >= the number of rows in time. You can add some print statements in the loop to see exactly what is happening, and then you will need to figure out how to handle that case, if it is legitimate.
