				FOR IN DO

FOR .. IN (..) DO is an internal command used in BATCH files or entered from
the keyboard to repeat a command for each of a set of values.

    FOR %%variable IN (set) DO command      ----- when used in BATCH files
    FOR %variable IN (set) DO command       ----- when entered at the keyboard

<variable> is some non-numeric character (usually a letter).

<set> can be any text string (without |, ), >, or <), a list of filenames of
    the form [d:][pathname]filename[.ext], possibly with wildcards in them, or
    even (in a BATCH file) environment variables. The values in <set> must be
    separated by " ", ";" or tabs.

<command> is any DOS command, program, or BATCH command except FOR. Piping and
    redirection may not always work as expected. FOR commands may not be
    directly nested (see EXAMPLES for a way to nest them).

When a FOR command is executed, <command> is executed once for each value in 
<set>, with <variable> in the command replaced by that value.
