You can't output to row1 because it is gone. You can however read the variable into and enumerated variable list and then output.

The data ( under CRADS ) has five lines, the 2nd and 3rd lines are the 40 observations of SST, each has length 4; the 4th and 5th lines are the 40 observations of ICE (character of length 3) . > > If read-in correctly, the variables SST and ICE should appear in pairs that the resulting SAS dataset should have only 40 rows.
