    The text quoted below should reference internal variables:

    @LINES also sets two environment variables:

    %_LINES_MAXLEN The length of the longest line (in characters)
    %_LINES_MAXLOC The line number (base 0) of the longest line

    Are there any other environment variables with names conforming to the internal variable name format (i.e., leading underscore character)?

    Does that mean that they can be unset, and one can check whether or not they exist with the if defined test?

    Of course, I meant built into TCMD or TCC! Even in 4DOS it was stated that one can even override an internal variable by defining an identically name environment variable, so naturally, I did not mean user defined ones.
