    APDL Command: /FORMAT

    Parameters
    ----------
    ndigit
        Number of digits (3 to 32) in first table column (usually the node
        or element number).  Initially defaults to 7.

    ftype
        FORTRAN format types (initially defaults to G):

        G - Gxx.yy.  xx and yy are described below.

        F - Fxx.yy

        E - Exx.yy

    nwidth
        Total width (9 to 32) of the field (the xx in Ftype).  Initially
        defaults to 12.

    dsignf
        Number of digits after the decimal point (yy in F or E format) or
        number of significant digits in G format.  Range is 2 to xx-7 for
        Ftype = G or E; and 0 to xx-4 for Ftype = F.  Initially defaults to
        5.

    line
        Number of lines (11 minimum) per page.  Defaults to ILINE or BLINE
        from the /PAGE command.

    char
        Number of characters (41 to 240, system-dependent) per line before
        wraparound.  Defaults to ICHAR or BCHAR from the /PAGE command.

    Notes
    -----
    Specifies various format controls for tables printed with the POST1
    PRNSOL, PRESOL, PRETAB, PRRSOL, PRPATH, and CYCCALC commands.  A blank
    (or out-of-range) field on the command retains the current setting.
    Issue /FORMAT,STAT to display the current settings.  Issue /FORMAT,DEFA
    to reestablish the initial default specifications.

    For the POST26 PRVAR command, the Ftype, NWIDTH, and DSIGNF fields
    control the time output format.

    This command is valid in any processor.
