- foreach varname list body
-
-
- DESCRIPTION
- 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.
