To enable ODBC for data access in PL/I, you must install the ODBC Driver Manager and drivers by selecting the "ODBC Drivers" component during installation.
A file named ivib.lic is installed in x:\plidir\ODBC, where x and plidir are the drive and directory respectively, where PL/I for Windows is installed.
You must keep this file in the install directory because it is used when you run your application to verify that you are licensed to use the ODBC driver. In Setting licensing information for ODBC Driver Manager/driver you learn how to use a function call to trigger the verification.
