SNAX/XF Utility

Overview

The SNAX/XF utility program (SNAXUTL) supplied with LUNS provides the means

for creating and maintaining the ESS, SET and BIND tables. With it, you can create a

new table or add and delete records in an existing table. Table 1-1 is a summary of

SNAXUTL command verbs.

Table 1-1. SNAXUTL Command Verbs

Verb Function

ADD Adds a record to a configuration table

ALLOCATE Allocates disk space for both the table’s source and object files

BEGIN Delimits the beginning of a command block

DELETE Deletes a record from a configuration table

END Delimits the end of a command block

SELECTFILE Selects or names the source file upon which subsequent commands are

performed

Creating a New ESS Table In creating a new ESS table, you use the SELECTFILE ESS command to give the table a

name and the ALLOCATE command to allocate disk space for it. Subsequent ADD

commands build each of the table’s records.

In adding records to an existing table, you use the SELECTFILE command to select the

table you wish to augment. A series of ADD commands builds the new records.

Within an ADD command, the verb ADD is followed by:

A modifier, defined by SNAXUTL syntax, that specifies the type of record being

added.

An object that you provide as a record-name field and that serves as a key to the

record.

Operands defining other fields within the record. These operands have two parts:

the operand name (a keyword defined by SNAXUTL syntax) and the operand data

(specifications you supply).

The formal syntax is:

verb

[

modifier

[

object

[

operand

...]]]]

You enter a series of such commands into an EDIT command file. Input commands

are free-format and allow for inclusion of comments. BEGIN and END commands

must, however, enclose all command blocks.

The following example shows a SNAXUTL command block that creates a new ESS

table with character-coded logon records for a TACL process and a Pathway

application, both residing on a local Tandem system.
