The EXPORT/IMPORT trick will work at least with test data. It is not
the best. PROC IMPORT is takes a long time.
dm 'clear log; clear output;';
data work.test;
array chr[381] $8 (381*'Hello');
array num[300] $8;
do _n_ = 1 to dim(num);
num[_n_]=put(ranuni(0),best8.);
end;
do _n_ = 1 to 1e3;
output;
end;
run;
proc print data=_last_(obs=2);
run;
filename ft56f001 temp lrecl=32707;
proc export data=work.test outfile=ft56f001 dbms=dlm;
delimiter=',';
run;
proc import datafile=ft56f001 out=work.test2 replace dbms=dlm;
delimiter=',';
guessingrows=1000;
run;
proc contents varnum;
run;
