Using the Command Line Required and Optional Parameters Command parameters can be optional or required. If a parameter is required, a value must be entered on the command line or the command will not execute correctly. If a parameter is optional, its value can be omitted and the system will substitute a default value. For example, the command STATUS has one optional parameter. If the command: STATUS ↵ is entered, status information for all the used system tasks will be displayed. If the command: STATUS 1 ↵ is entered, status information will be displayed only for system task number 1. If one or more parameters follow an omitted parameter, the parameter separator(s) must be typed.
If all the parameters following an omitted parameter are optional, and those parameters are also omitted, the separators do not need to be typed (see below for an example). Using the ID Command The ID command displays identity information about the components of the system: Software: version.revision opt1-opt2 Controller: model-serial options Processor n: version.revision type-options memMb Robot n: model-serial options module A sample display from the command "ID" is: Software: 16.4 87-31E0 (Edit D3, 10-May-2007, Maintenance Release) Controller: 2000-394 105 0 Processor 1: 0.52 7-7 32MB Robot 1: 100-0 0 8 For more detailed information, see the eV+ Operating System Reference Guide .
Monitor Command Syntax Conventions To help present the required syntax in the clearest, simplest manner, this manual uses the following syntax conventions: l The command name is shown in capital letters. l Parameters shown in bold lowercase letters are required and should be replaced with values you provide. For example, drive should be replaced with a drive letter you choose. l Parameters shown in non-bold lowercase letters are optional. If you omit an optional parameter, the system will use a default value. eV+Operating System User's Guide, v2.x, 18320-000 Rev A Page 27
