6.1 STD:Top File

Each Bunao script must begin with STD:Top File. It is the only module at the top level of the script hierarchy, and is the first module that Bunao evaluates when running a script. All of its children are globule definitions. See section STD:Globule Definition.

Use the Main Glob field to set the name of the globule that Bunao should execute first. By default, this is set to `Main' (and the STD:Globule Definition module defining `Main' is already created as the first child below STD:Top File.

The checkbox Allow standalone Unix shell execution lets this Bunao module be executed simply by typing its name at the command line. For example, to execute a script saved as `myscript.tcl', simply type:

% myscript.tcl

Without the standalone option enabled, the script must be explicitly passed as an argument to the Tcl interpreter, tclsh:

% tclsh myscript.tcl

By default, standalone execution is enabled.
