Sample ESS Table Records
Figure 1-3 shows an ESS table containing several types of logon records and an order
record. Note that logon records might contain fields that specify additional session
parameters.

ORDERENTRY, PLUNAME #CREATE, CONCDATA "params" . . . . . . . . . . .
A logon record for a Pathway application (type = LOGON-CHAR). This record relates the
character codedcommand ORDERENTRY to the Tandem Creator process's logical name
#CREATE. The record also contains a concatenated data field specifying Pathway
parameters to be passed to the Creator process.
A logon record for a Tandem TACL process (type = LOGON-CHAR). This record relates
the character coded command TACL to the application's logical name #TACL. The
record also contains a concatenated data field specifying NEWPROCESS parameters to
be passed to the Creator process.
A logon record for a host application (type = INITSELF-RECEIVED). The DLU name in
the record name (INV) identifies a host process. Note that one field (SENDHOST Y) must
specify that the logon request should be sent to the host; another specifies a gateway line
for the passthrough session.
A logon record for a host application (type = LOGON-INIT). This record relates the
character-coded command TSO1 to a host process whose DLU name is TSO. Note that
one field (SENDHOST Y) must specify that the logon request should be sent to the host;
another specifies a gateway line for the passthrough session.
An order record (type = ORDER). This record causes LUNS to set up a host SSCP-LU
session upon receipt of the character-coded command HOST.

Note that more than one active ESS table can exist within a Tandem system. For more
information, see the following subsection.
Additional parameters and the use of multiple ESS tables are discussed fully under
“Building the ESS Tables” in Section 2.
