Tom Brocker, IBM TPF ID Core Team, and Mike DeCarlo, Rob
Dunn, Takao Inouye, and Scott Vento, IBM TPFDF Development
TPFDF PUT 13 (APAR PQ30389) gives TPFDF users the option of
using a standard ZUDFM command syntax format instead of the
traditional (OA) format to improve usability.
The following lists the ZUDFM commands in the traditional and
standard formats:

APAR PQ30389 also provides the new ZUDFM OAB (traditional
format) or ZUDFM INFO (standard format) command to display block
trailer information for a single data block. In the following
example, the ZUDFM INFO command is used to display block trailer
information for a linked file:
USER: ZUDFM INFO
SYSTEM: CSMP0097I 17.40.18 CPU-B SS-BSS SSU-HPN IS-01
UDFM0184I TPFDF BLOCK TRAILER INFO F.A. F40640F4
FILE ID B075
PRIME ADDRESS F40640F4
OWN ADDRESS F40640F4
PROGRAM BASE FF00 HPN
DATA BASE FF00 HPN
SUBSYSTEM USER FF00 HPN
LAST COMMAND DBCKP
FILING PROGRAM QXDG
FILING CPU ID B
FILING I-S 1
FILING TIME TH 13JAN2000 17.39.49
END OF DISPLAY
With APAR PQ30389, you must still use the ZUDFM OAH command
(traditional format) with the INIT parameter specified to
initialize the help database before using the ZUDFM OAH command for
help. However, when you use the ZUDFM HELP or ZUDFM ? command
(standard formats), you must specify the new BUILD parameter to
initialize the help database before using either command for
help.
In the following examples, the help database is initialized by
using the ZUDFM OAH command (traditional format) with the INIT
parameter specified, and then the block trailer help information is
displayed by using the ZUDFM OAH command with the OAB parameter
specified:
USER: ZUDFM OAHINIT
SYSTEM: UDFM0244I 17.50.50 HLP-DATA BASE BUILT
END OF DISPLAY
USER: ZUDFM OAHOAB
SYSTEM: UDFM0243I TPFDF HELP FACILITY

In the following examples, the help database is initialized by
using the ZUDFM HELP command (standard format) with the BUILD
parameter specified, and then the block trailer help information is
displayed by using the ZUDFM HELP command with the INFO parameter
specified:
USER: ZUDFM HELP BUILD
