        HISTO_SIMPLE

    Computes the histogram of an image (or of a table).   A  subset  of  the
    image   may   be   specified.    The  result is a table with 2 columns :
    Column 1 contains the middle value of the  interval,  Column 2  contains
    the number of input image pixels in the interval.
2 Y_NAME$
        TASK\FILE "Input image" Y_NAME$

    This is the name of the input image.
2 Y_BLC$
        TASK\INTEGER "Bottom left corner" Y_BLC$[4]

    This is the Bottom Left Corner (in pixels) of  the  part  of  the  input
    image on which the histogram is computed.
2 Y_TRC$
        TASK\INTEGER "Top right corner" Y_TRC$[4]

    This is the Top Right Corner (in pixels) of the part of the input  image
    on which the histogram is computed.
2 X_BIN$
        TASK\INTEGER "Number of histograms bins" X_BINS$

    This is the number of bins that will be used in the histogram.
2 X_MIN$
        TASK\REAL "Minimum value" X_MIN$

    This is the lowest value used in the histogram.
2 X_MAX$
        TASK\REAL "Maximum value" X_MAX$

    This is the highest value used in the histogram.
2 X_NAME$
        TASK\FILE "Output histogram name" X_NAME$

    This is the name of the output histogram.
