Hello Linlin, Arthur and everyone, Linlin, thanks for the answer, but it is not so simple. I saw that you just created new one with setting older, but I have to manage with do list macro, and dates, such as: let br=30 do %i=1 %to &br %global datum and something like put(dates.....???) run; %put &br,datum&i; something like that This is only part of loop. I have 30 same tables ( same fields, but different values in it, name of one table is daily_product_01092013,...,daily_product_30092013) because in that tables we collect values from month to month and I would like to do append tables on cleverly way with macro coding ( I know to use EG and I now to use commands and tabs) Best!
