SYNOPSIS

_________________________________________________________________

DESCRIPTION
       Eval  takes  one  or more arguments, which together comprise a Tcl script containing one or more commands.  Eval concatenates all its argu-
       ments in the same fashion as the concat command, passes the concatenated string to the Tcl interpreter recursively, and returns the  result
       of that evaluation (or any error generated by it).

KEYWORDS
