1    /FILL

       /FILL=("*","O","x","@",":","#","/","+")

    Specifies the fill to be used for the first, second, etc., data
    kind in a plot. A maximum of eight character strings can be
    defined, and each must be delimited by double or single quotation
    marks.

    Note that /FILL=("*","O","x","@",":","#","/","+"), /NOSCALE and
    /NOWRAP are the default design qualifiers.

2    /SCALE

       /SCALE=n
       /NOSCALE

    Determines whether fixed or adjusted histogram scale is used.
    The /SCALE=n qualifier allows you to select a fixed scale for the
    plot. The /NOSCALE default qualifier selects adjusted scaling,
    which causes the longest bar on the histogram to occupy the full
    width of the plot.

    Note that /FILL=("*","O","x","@",":","#","/","+"), /NOSCALE and
    /NOWRAP are the default design qualifiers.

3    /WRAP

       /WRAP
       /NOWRAP

    Specifies to wrap PLOT output that is too long. /NOWRAP specifies
    to truncate PLOT output that is too long.

    Note that /FILL=("*","O","x","@",":","#","/","+"), /NOSCALE and
    /NOWRAP are the default design qualifiers.
