Using or Creating Files
Using or Creating Files -- Interface with the UNIX Operating System
Several commands, noted below and in the SAS documentation, use
or create UNIX files for your convenience. In general, UNIX
files are specified in SAS programs inside single quotes. Files
in the current directory -- i.e., the directory where you invoked
SAS -- may be specified by their file name alone. Files in other
subdirectories must be specified with the full pathname. Of
course, the full pathname may be used even when files are in the
current subdirectory. You may use the ~/ convention to stand in
for your home directory path. Each of the sections below dealing
with external files has an example or two showing how to specify
file names in SAS commands.
