SYMUPDTE has not existed for many years. There is IEASYMUP. If you are
using SYMUPDTE, I suggest that you change.
"Supported" is an interesting term. I might say that "supported" means
documented and that we will take an APAR if there is an error. I might say
that IEASYMUP meets both of those qualifications. The documentation is in
the Redbook and, as with any sample, we will take APARs if there is an
error. But I know that's not what you had in mind, and having to linkedit
IEASYMUP yourself is far from ideal.
As to "why not yet", it is in part because we had asked for, but until the
Share requirement mentioned had not received, a requirement that said that
it was OK not to have remote systems update their copies of the symbols
from "this system" when "this system" changed symbols (whether added or
deleted). That is the expensive thing, and is a logical step, but is not
clear when we would choose to spend the resources to implement it. This is
the thing that IEASYMUP does not do.
Are the return codes really not documented in the Redbook? Sorry about
that.
(hex)
00000000 - Success
00000008 - No parameter provided
nnnnnn0C - Symbol name contains ampersand
nnnnnn10 - Symbol name length, without ampersand,
is not 1-8
nnnnnn14 - Symbol value length > symbol name length
minus 1
00000018 - Too many symbols (maximum number of
symbols is exceeded)
nnnnnn1C - Reserved symbol
nnnnnn20 - Security product denied access
nnnnnn24 - Symbol value contains ampersand
In the info above, "nnnnnn" is a 1-origin number identifying which symbol
the processing did not like.
By the way: If / When updating of symbols is "fully supported", it might
not be via an EXEC PGM= program such as IEASYMUP. If IEASYMUP is
supplanted by another mechanism, a new IEASYMUP might be provided which
does nothing more than return a new return code indicating "do not use
me". We would not be able reasonably to do much more than warn / alert
you not to use an "old" IEASYMUP as an old IEASYMUP might not build the
control structures expected.
