## GR8_BLANKING

`GR8_BLANKING(BVAL,EVAL)`

Define the blanking value to be used later. It is equivalent to call `GR_EXEC('SET BLANKING BVAL EVAL')`, but the later form requires formatting of values.

    Arguments :
            BVAL    REAL            Input   Blanking value
            EVAL    REAL            Input   Blanking precision
