| Using the SAS/ACCESS Interface to CA-IDMS |
Guidelines for Using the CA-IDMS INFILE Statement and DML Function Calls
You access CA-IDMS records and sets, one record at a time, using the CA-IDMS INFILE and INPUT statements.
By specifying options on the INFILE statement, you can generate navigational DML calls to CA-IDMS. To issue the appropriate DML calls, you need a thorough knowledge of the database structure.
The CA-IDMS access method that you need to use depends on how the sets were defined to the database. The access methods are CALC, CURRENT, DBKEY, OWNER, SORT KEY, or WITHIN.
The DATA step interface determines what type of access method to generate the calls for, based on the DML function call and options that you specify in the INFILE statement. Valid DML functions are OBTAIN, FIND, BIND, ACCEPT, GET, IF, and RETURN. The OBTAIN and GET functions are the only functions that retrieve a record's contents from the database.
