NOTE:
The XL compiler evaluations listed above contain the full functionality of the licensed version except that they will stop working 60 days after they have been installed. Unlike other IBM software products which use license keys to enable the product once licenses have been purchased, XL compilers require a licensed version to be installed to replace the evaluation version. The licensed version of the software can be downloaded from the IBM Passport Advantage site if installation media on CDROM was not purchased when the licenses were purchased. One must uninstall the evaluation version of the compiler and then install the licensed version of the compiler software, before being able to continue using the compiler software.
