Accessing External Files

Using the INFILE/FILE User Exit Facility

User exit modules enable you to inspect, modify, delete, or insert records in a DATA step. Here are some examples of how they can be used:

  • encrypting and decrypting data

  • compressing and decompressing data

  • translating data from one character encoding to another.

User exit modules are an advanced topic. See Sample Program for details.
