- The compiler now handles even more conversions by generating
inline code which means these conversions will be done much faster
than previously. Also, all conversions done by library call are
now flagged by the compiler.
- The compiler-generated code now uses, in various situations,
less stack storage.
- The compiler now generates much better code for references to
the TRANSLATE built-in function.
- The compiler-generated code for SUBSCRIPTRANGE checking is now,
for arrays with known bounds, twice as fast as before.
- The ARCH and TUNE options now support 4 as a suboption, thereby
allowing exploitation of instructions new to the zSeries machines.
- ARCH(2), FLOAT(AFP) and TUNE(3) are now the default.
