This Natural profile parameter is used to specify the parameters for
the Natural TSO Interface. It corresponds to the macro
NTTSOP
in
the Natural
parameter module.
Possible settings | See TSOP Parameter Syntax. | |
---|---|---|
Default setting | See Keyword Subparameters. | |
Dynamic specification | yes | The parameter TSOP can only be
specified dynamically. In the
Natural
parameter module, use the macro
NTTSOP .
|
Specification within session | no |
The following topics are covered:
The TSOP
parameter is specified as
follows:
TSOP=(keyword-subparameter=value,keyword-subparameter=value,...) |
For information on subparameter names and values, see Keyword Subparameters.
The NTTSOP
macro is specified as follows:
NTTSOP ABEXIT=value, * ALTSCRN=value, * LBPNAME=value, * LEHDLR=value, * NDBFSRV=value, * PA2=value, * SUBPOOL=value, * SWAPKEY=value, * TIOBSZ=value

ABEXIT=value
specifies the
mode of abend processing within Natural.
Value | Explanation |
---|---|
ESTAE |
Natural intercepts all abends and
issues the appropriate error messages.
This is the default value. |
SPIE |
Only program checks
(S0Cx abends) are intercepted.
|
OFF |
Natural does not intercept any abends or program checks at all. |
Notes:
ABEXIT=OFF
corresponds to profile
parameter DU
=FORCE
.
ABEXIT=OFF
is not recommended
because some functions, which require the abend interception, will not work any
longer. The usage of profile parameter MT
will cause an abend
U0322
instead of error NAT0953 when the CPU time limit is
reached.
ALTSCRN=value
specifies
whether the 3270 alternate screen size is to be used.
Value | Explanation |
---|---|
ON |
The alternate screen size is to be
used.
This is the default value. |
OFF |
The default screen size is to be used. |
Notes:
TMODEL
.
LBPNAME=value
controls the
sharing of the local buffer pool when running multiple Natural sessions within
the same TSO region. It defines the name of the shared buffer pool environment
and is used to locate the shared local buffer pool.
Value | Explanation |
---|---|
1 - 8 characters |
Name of the shared buffer pool. |
' ' (blank) | The local buffer pools are not shared.
This is the default value. |
Note:
When running multiple Natural sessions in a z/OS batch or TSO
region concurrently, each session allocates storage for a separate local buffer
pool. Except for the Natural z/OS batch mode server, the local buffer pools are
not shared by default; that is, if the different sessions use the same Natural
objects, these have to be loaded once for each session separately. If a shared
buffer pool name is specified, all Natural sessions will share the same local
buffer pool.
LEHDLR=value
specifies
whether Natural uses an LE error handler for the call of LE subprograms.
Value | Explanation |
---|---|
ON |
An LE error handler is set up by
Natural during the call of LE subprograms. This means, if an unhandled LE error
occurs during the execution of an LE subprogram, Natural will get control and
can handle it (by issuing error NAT0954).
This is the default value. |
OFF
|
No setting of an LE error handler is done by Natural during the call of LE subprograms. This means, if an unhandled error occurs during the execution of a LE subprogram, the LE enclave is terminated and so the Natural session is lost. |
Notes:
NATLEOPT
in the Installation for
z/OS documentation.
NDBFSRV=value
specifies
whether the Natural for DB2 file server is to be used.
Value | Explanation |
---|---|
OFF |
The Natural for DB2 file server will
not be used.
This is the default value. |
ON |
The Natural for DB2 file server is invoked at each terminal I/O. |
PA2=value
specifies how
the PA2 key shall work.
Value | Explanation |
---|---|
ON |
The PA2 key value is passed to the Natural application. |
OFF |
The PA2 key value is used to
redisplay the terminal screen and is not passed to the Natural application.
This is the default value. |
Note:
The PA2
subparameter specification is
irrelevant if the PA2 key is defined as the split screen swap key by
subparameter SWAPKEY
.
SUBPOOL=value
defines the
storage subpool for GETMAIN
requests.
Value | Explanation |
---|---|
1 - 127 |
Subpool number. |
0 |
This is the default value. |
Notes:
SUBPOOL
is honored
only in the Natural parameter module which is linked to the TSO
driver, but not in an alternative parameter module which is activated using a
PARM=
specification.
SUBPOOL
is
evaluated during session initialization only, it cannot be specified as a
dynamic subparameter.
SWAPKEY=value
defines the
TSO/ISPF split screen swap key for Natural, which is assigned to PF9
on most of the panels of Software AG product Natural ISPF (Integrated
Structured Programming Facility).
Value | Explanation |
---|---|
PF1 - PF24 | Defines the PF- or PA-key which shall be used to swap to the next TSO/ISPF session. |
PA1 - PA3 | |
OFF |
By default, no swap key is defined; that is, no split screen feature support is generated. |
Notes:
SWAP
command in TSO/ISPF is assigned to
the PF9 key on most TSO/ISPF panels.
ISPLINK
from the ISPF load library. You can include
ISPLNK
in the link step for NATTSO
. If not linked,
Natural tries to load it dynamically when the key defined with
SWAPKEY
is first used in the session. If
ISPLINK
is not contained in the load library, Natural treats
SWAPKEY
as set to OFF
.
TIOBSZ=value
specifies the
size of the terminal I/O buffer.
Value | Explanation |
---|---|
4 - 32 |
Size of the terminal I/O buffer in KB. |
8 |
This is the default setting. |
Note:
The terminal I/O buffer is allocated below the 16 MB line.
