Setting the Current Volume or Directory

When you set the current working volume or directory using the

(change

directory) command, you are setting the global variable “PWD” to the value you

specify in the command, as shown in the following script:

cd 3:

echo $PWD

getenv PWD

PWD = “3:”

Controlling Program Flow

The Technician Interface provides several commands to control program flow in

your script. For details on each of the following commands, see Chapter 2.

• To specify the next line to be executed from the script file, use the

goto

command.

Within the script file, use the

goto

command with a label. A label begins and

ends with a colon (:), consists of up to 15 alphanumeric characters and the

underscore character (_), and must be on its own line, beginning in column 1.

• To evaluate whether an expression is true, use the

command. The expression

can compare two numerical values or two ASCII strings. If the expression is

true, the script interpreter executes any additional commands that are on the

same command line as the

command. If the expression is false, the script

interpreter does not execute the

command.

You use a semicolon (;) to end an

command. The semicolon separates the

command from the commands you want executed if the

command is true.

• To suspend the Technician Interface’s operation for a given interval, use the

pause

command. During this time the router is still running.

• To call a subroutine inside the same script file, use the

gosub

command. It

must be the last command on a line. You can nest subroutines up to 10 deep.

You use the

return

command in a subroutine to return to the calling routine.

When the

return

command executes, the script interpreter begins executing

the instructions on the line following the line containing the

gosub

command.
