Command Prefixes

The following prefixes can be used with the Bricscad commands:

Prefix	Type	Result
' (single quote or apostrophe)	Transparency	Allows a command to be executed inside another command. E.g. If you are drawing a line, type 'zoom at the command prompt to temporarily interrupt the LINE command while executing the ZOOM command.
- (dash)	Command line	Launches a non-dialog version of a command. All command options are available in the command bar. E.G. Type -layer at the command prompt to suppress the Drawing Explorer / Layers dialog. All command options are available in the command bar. This is especially useful if you need to execute such commands in a script.
_ (underscore)	Global	Executes the original English command (global command) in translated version of Bricscad. It is recommended to use the global command prefix in scripts, or when defining keyboard shortcuts or customized tools.
. (period)	Non-redefined	Executes command that have been undefined using the UNDEFINE command.

Command prefixes can be combined. E.g. to execute a global command transparently: '_snapang sets the SNAPANG variable transparently in a translated version of Bricscad.
