PL/I Syntax

The internal representations of floating point constants on the Sun versions of Open PL/I are sometimes different from those on the IBM RS6000.
The compiler does not diagnose a mismatch between actual parameters and the parameter list in the entry declaration when the dimension attribute is used in the parameter list.
No diagnostic is generated when you pass an array argument to a non-array parameter.
Static initialization of a pointer to the address of a static data item is not supported.
The PUT FILE statement adds an extra character in front of the data being written into a file.
Prior to Enterprise Developer 2.2, if using the -cics, -ims, or -mvs options when compiling with mfplx on a little endian platform, the possibility for errors existed. Starting with Enterprise Developer 2.2,-cics, -ims, or -mvs options when compiling with mfplx automatically also uses -bigendian, thereby eliminating the possibility for these errors.
Evaluate any applications built using a prior release to determine any impact on any data files being used.
