Deﬁning a Pseudo-Variable Array

The Technician Interface script facility allows you to deﬁne a pseudo-variable

array. A true array is a set of consecutive memory locations used to store data.

Each item in the array is called an element. An element is a variable. To reference

an element of an array, you use a number called the index. In a pseudo-variable

array, the elements (variables) are not in consecutive memory locations. To create

a pseudo-array, use variable names that end in numbers (for example,

a1, a2, and

a3). The following script shows how to access a member of an array using an

index:

setenv a1 one

setenv a2 two

setenv a3 three

let index=2

echo “a[$index]=${a[$index]}”

a[2]=two

is displayed on the user’s console.

For speciﬁc instructions on using the commands in the previous example, see

Chapter 2.

Creating and Using Variables

This section explains how to view local and global variables, how to set variables,

and how to delete them.

Viewing Variables

You view the current list of variables stored in the local and global environment

variable tables using the

getenv command. For example, if you enter

getenv a

the system responds a = blue.

You can also use the

echo $

<variable_name>

command to view a variable.

For speciﬁc instructions on using the

getenv and echo commands, see Chapter 2.
