Additional Features
In addition to using the methods for appending raw
data files that were discussed earlier in this chapter, you can also
append raw data files using a SAS data set or an external file that
contains the names of the raw data files to be appended.
Storing Raw Data Filenames in a SAS Data Set
In the following program,
five raw data files, Route1.dat, Route2.dat, Route3.dat, Route4.dat,
and Route5.dat, are concatenated to create the SAS data set Work.NewRoute.
The names of the raw data files are stored in the SAS data set Sasuser.Rawdata,
which is referenced using a SET statement. The name of the FILEVAR=
variable, Readit, is the name of the variable in Sasuser.Rawdata whose
value is the name of the file to be read.
