/TOKEN=keyword

    Changes the maximum size of tokens (elements) in a DCL command.
    (A token is any element in a command line that is bounded by
    spaces. For example, the command COPY X.TXT Y.TXT contains three
    tokens.) The token size is determined by the setting of bit 1 in
    the DCL_CTLFLAGS system parameter. By default, the bit is clear,
    indicating that traditional tokens (255 bytes) are being used.
    If the bit is set, extended tokens (4000 bytes) are used. The
    corresponding keywords for /TOKEN are TRADITIONAL and EXTENDED.
    You can use SHOW PROCESS/TOKEN to determine the current token
    size setting.
