Thanks, Stan, for continuing to humor me with this, and for your detailed
example demonstrating that it works properly on 6.0 with C.07.14 Image.
<plug?> BTW, your DBDRIVER program looks like a great tool.</plug?>
Can anybody confirm or refute my assertion that it does NOT work under MPE
5.5pp7 and Image c.07.04 (version # from DBUTIL banner)? It looks to me
that I'm doing exactly what Stan's doing, but it doesn't work for me!
"It" is...
DBFIND mode 1 vs indexed-masterset arg "@"
DBGET mode 5 vs indexed-masterset
...works great, returns the lowest-key-value record. But...
DBFIND mode 1 vs indexed-masterset arg "@"
DBGET mode 6 vs indexed-masterset
...returns an immediate beginning-of-chain (status 14), but should (as
demo'd by Stan) return the highest-value record.
In greater detail, my pgm does this relevant stuff...
DBINFO MODE=+0113
STATUS=+0000
WORD 1 = +0001
WORD 4 = +0000
WORD 5 = +0001
WORD 5R= @
DBINFO MODE=+0209 SET=FLEET-MASTER
status=+0000
Word1=+0001
Word2=+0000
...(which says yes the btrees are ok for this set and use @ for the
wildcard), so...
DBFIND:mode=+0001;set=FLEET-MASTER;search=FLEET;arg=@;status=+0000
DBGET:mode=+0006;set=FLEET-MASTER;status=+0014
DBFIND:mode=+0001;set=FLEET-MASTER;search=FLEET;arg=@;status=+0000
DBGET:mode=+0005;set=FLEET-MASTER;status=+0000
