     NAME
          for - ``For'' loop

     SYNOPSIS
          for start test next body
     _________________________________________________________________


     DESCRIPTION
          For is a looping command, similar in structure to the C  for
          statement.   The start, next, and body arguments must be Tcl
          command strings, and test is an expression string.  The  for
          command  first invokes the Tcl interpreter to execute start.
          Then it repeatedly evaluates test as an expression;  if  the
          result  is  non-zero it invokes the Tcl interpreter on body,
          then invokes the Tcl interpreter on next, then  repeats  the
          loop.   The command terminates when test evaluates to 0.  If
          a continue command is invoked within body then any remaining
          commands  in  the  current  execution  of  body are skipped;
          processing continues by  invoking  the  Tcl  interpreter  on
          next,  then  evaluating test, and so on.  If a break command
          is invoked within body or next, then the  for  command  will
          return immediately.  The operation of break and continue are
          similar to the corresponding statements in C.   For  returns
          an empty string.
