3. 0 Variables Scripts may contain variables. Variable names must begin with a letter or an underscore and may contain any sequence of upper- or lower-case letters, digits, and underscores. You cannot use a reserved word as a variable name. For more information, see the list of reserved words at the end of this document. You must declare variables before you use them.
When you declare a variable, you must also define its type. A variable of a certain type may only contain values of that same type. The following three types of variables are supported: Type Description integer A negative or positive number, such as 7, -12, or 5698. string A series of characters enclosed in double-quotes; for example, “Hello world!” or “Enter password:” . boolean A logical boolean value of TRUE or FALSE. Variables are assigned values using the following assignment statement: variable = expression The variable gets the evaluated expression.
Examples: integer count = 5 integer timeout = (4 3) integer i boolean bD one = FALSE string szIP = (get ip 2) set ip addr szIP 3. 1 System Variables System variables are set by scripting commands or are determined by the information your enter when you set up a Dial-Up Networking connection. System variables are read-only, which means they cannot be changed within the script. The system variables are: Name Type Description $USERID String The user identification for the current connection.

This variable is the value of the user name specified in the Dial-Up Networking Connect To dialog box. $PASSWORD String The password for the current connection. This variable is the value of the user name specified in the Dial-Up Networking Connect To dialog box. $SUCCESS Boolean This variable is set by certain commands to indicate whe the or not the command succeeded. A script can make decisions based upon the value of this variable. $FAILURE Boolean This variable is set by certain commands to indicate whether or not the command failed.
A script can make decisions based upon the value of this variable. These variables may be used wherever an expression of a similar type is used. For example, transmit $USERID is a valid command because $USERID is a variable of type string. 4. 0 String Literals Scripting for Dial-Up Networking supports escape sequences and caret translations, as described below.
String Literal Description ^char Caret translation If char is a value between ‘@’ and ”, the character sequence is translated into a single-byte value between 0 and 31. For example, ^M is converted to a carriage return. If char is a value between a and z, the character sequence is translated into a single-byte value between 1 and 26. If char is any other value, the character sequence is not specially treated.
Carriage return Linefeed ” Double-quote ^ Single caret < Single ' = Relational Integers = = ! = Equality Integers, strings, booleans and Logical AND Booleans or Logical OR Booleans Examples: count = 3 + 5 40 transmit "Hello" + " there" delay 24 / (7 - 1).
