_________________________________________________________________

yz DESCRIPTION
       除非正在解釋一     Tcl     過程否則忽略這茤R令。如果正在解釋一    Tcl
       過程,則它聲明這些給定的                                        varname
       是全局變量而不是局部變量。全局變量是在全局名字空間中的變量。在這-
       虓礅e過程的持續期間(duration)(並且只有在當前過程中執行的時),對
       varname 中任何一茠漸籉韝犍帠ㄠN參照(refer to)叫相同名字的全局變量。

       Please  note  that  this  is  done by creating local variables that are
       linked to the global variables, and therefore that these variables will
       be listed by info locals like all other local variables.
