Customizing the User Environment

In addition to the semicolon, there are other operators you can use to form

compound strings (in other words, to join text and identiﬁer variables into

one command). These operators are listed in Table 5-5 in order of

precedence.

Examples

• To display the message “Hello,” add the following line to the login script:

WRITE “Hello”

• To display the user’s last name (surname) along with a greeting, add the identifier

LAST_NAME to the command. To do this, either join the text and the identifier

with a semicolon or include the variable in the quotation marks with the text.

Either of the following lines displays “Hello, Smith” when user Bob Smith logs

in:

WRITE “Hello, ”;%LAST_NAME

WRITE “Hello, %LAST_NAME”

• To make a beep sound occur while the phrase “Good morning” appears on the

screen, add the following line to the login script:

WRITE “Good %GREETING_TIME \7”
