You can append the following prefixes to all AutoCAD commands and options in order to avoid localization issues:
An underscore _
This calls the English version of the command. For example, the command, _LINE, can be issued from all localized releases and English AutoCAD.
A period .
This calls the original command when a command was redefined. For example, whena user redefines the LINE command. In such a case, _.line can be issued from all localized releases and English AutoCAD. It will always invoke the original LINE command.
A hyphen -
This calls the command-line version of the command (when available). For example, _.-layer calls the command line version of the original layer command in all AutoCAD releases, independent of the localization.
