                 'Set'  can  be  used  to  assign  arbitrary  values to shell
                 variables.  The first argument is the name of  the  variable
                 to  be set; if absent, the value is printed on standard out-
                 put instead of being assigned.  The third  argument  is  the
                 value to be assigned to the variable; if absent, one line is
                 read  from standard input, and the text thus entered becomes
          |      the  string  to  be  assigned.   The  string   may   contain
          |      unprintable characters in a mnemonic form.  This consists of
          |      a '<' sign followed by an ascii mnemonic and terminated by a
          |      '>'  symbol.   To  prevent  a symbol from being interpreted,
          |      simply escape the '<' with and '@' sign.  For example to set
          |      the variable lfcr to a linefeed and a carriage return, use:

          |           set lfcr = "<lf><cr>".

                 If <variable> exists in the current scope or any surrounding
                 scope, then its value is altered by 'set'; otherwise, it  is
                 created  at  the current lexical level and then the value is
                 assigned.
