Using Environment Variables; Set Envar And Show Envar Commands - Compaq AlphaServer 1200 User Manual

4.12 Using Environment Variables

Environment variables pass configuration information between the console and
the operating system. Their settings determine how the system powers up, boots
the operating system, and operates. You issue an init command to activate a
new environment variable.
Example 4-23 Set envar and Show envar Commands
P00>>> show console
console
P00>>> set console serial
P00>>> show console
console
P00>>> init
Environment variables are set or changed with the set envar command and set to
default values with the set -default envar command. Their values are viewed with
the show envar command. User-defined nonvolatile environment variables are
created with the edit command described in Section 4.4. Section 4.18 describes the
environment variables in detail.
