To delete arguments from a Call Subroutine command:

1. Place the cursor on the CALLSUB command.

2. Press F9 to access the Call Subroutine dialog box.

3. From the list of arguments, select one or more arguments.

4. Click the Delete Arg button.

5. Click OK.

You can also delete an argument in the Edit window text directly. To do this,

1. Place PC-DMIS in Command mode.

2. Place the cursor on the CALLSUB command, and press TAB until you highlight the desired argument.

3. Type the letters "del" to delete the argument. Note that pressing Delete or Backspace doesn't truly delete the argument, they merely change the argument to an empty argument.
