It might be more efficient
to use a view descriptor to extract PC files data and place it in
a SAS data set.
-
A PC file is read every time a view Descriptor is referred
to in a SAS program and is executed. It is better to extract data
under these circumstances:
-
If the file is large and you use
the data repeatedly in SAS programs.
-
If you use sorted data several
times in a SAS program.
-
For added security, you can assign
a password to the extracted SAS data set.
