    ---Purpose : Sets a Global (Header) Parameter to a new value, directly given
    --           Controls the form of the parameter (Integer, Real, String
    --           with such or such form), but not the consistence of the new
    --           value regarding the rest of the file.
    --           
    --           The new value is given under the form of a HAsciiString, even
    --           for Integer or Real values. For String values, Hollerith forms
    --           are accepted but not mandatory
    --  Warning : a Null (not set) value is not accepted. For an empty string,
    --           give a Text Parameter which is empty
