In SAS, how do I create an ASCII text file from a SAS data set?

To create an ASCII text file from a SAS data set, use the FILE and PUT statements in a DATA step.

Suppose you have a SAS data file in the c:\sasdata directory called test.sas7bdat, which contains the five variables v1 through v5. You wish to store these variables in an ASCII file called test.txt. Consider the following SAS code:

The LIBNAME statement assigns a library reference (libref) to the location of the permanent SAS data set. This libref is given an alias of old. Once the library reference is set, you then open a data set in a DATA step. The SET statement reads the permanent SAS data set test from the library old. The data set (e.g., old.test) is referred in the form of libref.name, where libref is the alias set by a LIBNAME statement and name is the actual data file name without its extension.

The FILE statement declares a file in which SAS stores the output of the DATA step in the format specified in the PUT statement. For the listed format, the PUT statement is followed by a list of the variables you wish to store in the output file test.txt .
