foreach - Iterate over all elements in a list
foreach varname list body
In this command varname is the name of a variable, list
is a list of values to assign to varname, and body is a
Tcl script.
For each element of list (in order
from left to right), foreach assigns the contents of the
field to varname as if the lindex command had been used
to extract the field, then calls the Tcl interpreter to execute
body. The break and continue statements may be
invoked inside body, with the same effect as in the for
command. Foreach returns an empty string.
