- Wsid
An eight-character input byte array.
The Wsid parameter identifies your workstation. It must contain a
left-justified alphanumeric name beginning with a letter. If the
workstation identifier is less than eight characters long, it must
be followed by blanks.
- ChainSize
An input integer variable.
The ChainSize parameter contains the number of request units (RUs) to
send in one SNA chain, from 1 through 99. See "Glossary" for
a definition of RU. If the value of ChainSize is 0, the configured default value applies.
- LUNames
An input byte array. The
LUNames array is a list of eight-character logical unit (LU)
names. In MPE V, these are LU class names as configured in the SNA Configuration:
Classes screen. In MPE XL, these are host names (not NAUs) of LUs
that you wish to start. See "Glossary of Terms" for
the definition of an LU.
Each entry is left-justified, and blank-filled. The number
of entries is specified in LUNamesLen.
Following is an example of an LUNames array of four entries:
FIRSTLU
NEXTUNIT
NTHLU
LASTUNIT |
You cannot start an LUName that is already started.
- LUNamesLen
An input integer. The
LUNamesLen parameter specifies the number of entries in LUNames, from 0 through 16. The value of LUNamesLen for the LUNames example above is 4.
If the value of LUNamesLen is 0 and the workstation is inactive, the configured
auto-start LU names are initiated.
If LUNamesLen=0 and the workstation is active, a Result will indicate an error.
The maximum LUNamesLen value is 16.
- Traces
A two-element input integer array. Each
element of Traces contains an integer that represents a type of tracing
to turn on or off.
The use of two elements allows you to enable multiple trace
types simultaneously. The order of the elements is not significant. Traces element values are as follows:
1 = NRJE LU process tracing.
- TraceFileLen
An input integer. The
TraceFileLen parameter is the length in characters of the trace
file designator, TraceFile.
The number of characters may be between one and thirty-five.
If this parameter is zero, the trace is recorded in the DefaultFile.
- TraceMedium
An input integer. TraceMedium indicates the TraceFile device type. This parameter is called by reference.
The only valid value for TraceMedium is 0, which indicates that the trace information will
be written to a disk file.
- TraceSize
An input integer. TraceSize contains the maximum number of logical records TraceFile is to contain, from 0 through 32767.
A logical record is 128 words long. If TraceSize is zero, the default file size of 1024 records is used.
- TraceFile
An input byte array. The
TraceFile byte array contains an actual file designator used
for trace output. This parameter is used only when TraceFileLen is greater than zero. This parameter identifies a disk trace
output file. TraceFile can contain a fully qualified 35-character disk file
name, with lockword, in this form:
filename[lockword][groupname[acctname]] |
The contents of TraceFile must be left-justified, with trailing blanks, and meet
MPE standards for an actual file designator.
If you specify a disk file that does not exist (a NEW file), then it will be created as the destination
for trace output.
If you specify an OLD file (it already exists), and it already is in
use for trace output, then trace output records for this activity
are interleaved with other trace output records. You minimize the
use of disk space by using an OLD file appropriately; however, trace output can
be overwritten. If you specify an OLD file that is not already open, the file will be
overwritten with new trace data. No warning is issued. Trace file
records are created after successful completion of the intrinsic.
If an error is encountered during the execution of the intrinsic,
only the status array will be traced.
- DefaultFile
An output byte array. The
DefaultFile parameter is the file designator of the default trace
file. A default file name is created whenever TraceFileLen is zero.
Default file names are in the form NMTCnnnn.PUB.SYS, where nnnn is a four-digit number that is incremented each time
a default trace is created. Default file names are up to 27 bytes
long. The last character is always a blank. You can always retain
trace data by using a DefaultFile; however, considerable disk space might be used.
- Result
An eight-element integer output array
(required). The Result array contains error codes that occurred during execution
of this intrinsic.
The first element of the Result array is set to zero if no errors took place. The structure
of the Result array is described in "Parameters Common to
NRJE Intrinsics" in the introduction to Chapter 5 “User Intrinsics”
Always test the first element of Result immediately after you call this intrinsic. If the first
element of Result is not zero, test the other elements of Result to determine the nature of the problem that has occurred.
