In the Munich System z Technical University conference 2 weeks ago
Marna Walle mentioned that in z/OS 2.1 EXECIO is previewed to
perform I/O to VBS (as in "Spanned" :-) ) data sets.
Have they added the language enhancements in OOREXX, or at least those
in the ANSI standard?
Shmuel,
Unfortunately, any changes to the Rexx language standard that would
also require changes to the compiler preclude themselves. The compiler
is in the Dead Pool at IBM, functionally stabilized with no budget to
enhance it. I've tried and failed numerous times to get IBM to bring
Rexx up to ANSI standards. The enhancements you see to Rexx are all
done through external functions, like EXECIO. Those enhancements
require no compiler updates, so for now, that is all you will see as
far as Rexx enhancements go.
Then the REXX compiler is more trouble than it's worth. I ran some
simple EXECIO read I/O benchmarks and compiled REXX was the slowest of
the lot http://users.tpg.com.au/crayford/rexx-lua-c-io-benchmark.htm.
