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
| ALTSCRN
| LBPNAME
| LEHDLR
| NDBFSRV
| PA2
| SUBPOOL
| SWAPKEY
| TIOBSZ
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.
TSOP=(LBPNAME=NATTEST1,TIOBSZ=12,SWAPKEY=PF9)
