Using the Command Prompts
After you select the ETU command that you want to run, either by choosing an option from the menu or by entering the name of the command on the command line and pressing F4, a prompt screen displays. This screen lists the parameters associated with the command. A parameter is a placeholder for a single piece of information, or value, that you must provide to ETU to tell ETU what to do and how to do it.
When the prompt screen displays, enter a value for each parameter that applies to your transfer operation. For instance, when you transfer a host file to the microcomputer, you must provide, among other things, the name of the host file. You enter the name of the host file in the FROMFILE parameter. Thus, the host file name is the value to be entered in that parameter.
Some parameters contain preset values, called defaults. If you do not need to use a particular parameter, leave it at its default value. To view all the possible values for a particular parameter, enter a question mark (?) in the first position of the parameter, press FIELD EXIT, and then press ENTER. If there is a plus sign (
) next to the parameter keyword, the parameter can be extended for additional values. To enter the additional values, place the cursor next to 
for more, enter a plus sign, and press ENTER.
When you have filled out all the required parameters, press the ENTER key. If the command contains more than one screen of parameters (which some ETU commands do), press PAGE UP to display subsequent screens. To start the command, press ENTER.
Using Mac Directory Dialog Boxes
Mac directory dialog boxes are available for some ETU commands. A directory dialog box provides an alternative to entering a value into a menu's micro file name prompt.
You can specify the location of the Mac file by entering the file name at the QFNAME1 prompt, or you can display a dialog box. To display a dialog box, enter an asterisk (*) in the first position in the QFNAME1 prompt, fill out all other parameters required for the transfer operation, and press ENTER.
NOTE: The directory dialog boxes are unavailable for the DELETEB and RENAMEB procedures.
Use an ETU directory dialog box as you would use any standard Mac directory dialog box. For information about using directory dialog boxes, refer to your Mac System Software User's Guide.
NOTE: If you cancel from a dialog box, you receive an ETU user message giving you the option to CANCEL or GO. Select CANCEL to return to the WSMENUS options.
