Customizing the User Environment

Identiﬁer Variables

The SHIFT login script command allows you to change the order in which

these %n variables are substituted. For more information about the SHIFT

command, see “SHIFT” in this chapter.

The %n variables can be used in WRITE statements if they are included

within the quotation marks:

WRITE “My login name is %1.”

Example

Suppose a login script contains the following commands:

IF “%2”=“SALES” THEN

WRITE “Meeting today”

END

IF “%3”=“LEGAL” THEN

WRITE “Report is due tomorrow”

END

If user RON logged in by typing the following command:

then the login script would substitute the values Ron entered at the keyboard

for the %n variables in the login script, as shown here:

%0=COUNT

%1=RON

%2=SALES

%3=MARKETING

Since %2 is replaced by “SALES,” the message “Meeting today” is

displayed on Ron’s screen. However, since %3 is replaced by “Marketing,”

Ron doesn’t see “Report is due tomorrow.”
