Creating SAS Data Sets from External Files
explained how the PUT statement can be used with column output to
write observations from a SAS data set to a raw data file. The PUT
statement can also be used with list output to create free-format
raw data files.
List output is similar to list
input. With list output, you simply list the names of the variables
whose values you want to write. The PUT statement writes a value,
leaves a blank, and then writes the next value.
General form, PUT statement
using list output:
PUT variable <:
variable specifies the variable whose
value you want to write
format specifies a format to use for
writing the data values.
