This chapter describes a general strategy for moving your source programs to Enterprise PL/I. The following tasks are necessary, and should be performed in roughly the following order:
Because of the loss of service support for older PL/I compilers, you should eventually move all of your PL/I source programs to the new compiler. Although this is not an immediate requirement, at some future date the older compilers and any supported fixes will not be available. At that point, you will be forced to do a 'quick' migration, and this might be a very inconvenient time.
Before you can move your source programs to the new compiler, you must move your applications to Language Environment.
