foreach(3Tcl) foreach(3Tcl)
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.
