=== !MassList ===

{{{MassList}}} is a list of length 2, whose entries are
   1. The {{{BlockName}}} {{{MASS}}} for masses 
   1. A matrix: in each row you find 
      1. The pdg code of the particle (between curly brackets) 
      1. The symbol for the mass. 
      1. The numerival value ( {{{Internal}}} if the mass if given as an internal parameter, and {{{NoValue[1]}}} if no value is specified in the model file. 
 Notice that massless particles are not shown in {{{MassList}}}. 
=== !WidthList ===

Similar to {{{MassList}}}, except that the first element is the {{{BlockName}}} {{{DECAY}}}. Notice that stable particles (Γ{{{0) are not shown in =WidthList}}}.
=== !EParamList ===

{{{EParamList}}} is a list containing all external parameters defined in the model file. Each element of this list is a two-component list, corresponding to a LH block:
   1. The first element is the LH block 
   1. The second element is a list containing all the parameters in this block. 

Each parameter is given as a list:
   1. The LH block number (between curly brackets) 
   1. A list of length 4 or 6 giving all the properties of the parameter. 

If no {{{InteractionOrder}}} was specified for this parameter, then the length of the list is 4:
   1. The {{{ParameterName}}} of the parameter. 
   1. the numerical value 
   1. {{{True}}}/{{{False}}}, specifying whether the parameter is complex ( {{{True}}}) or not ( {{{False}}}). 
   1. a string, giving a description of the parameter. 

If an {{{InteractionOrder}}} was defined, then the length of the list is 6

   1. The {{{ParameterName}}} of the parameter. 
   1. The name of the {{{InteractionOrder}}} (usually {{{QED}}}/{{{QCD}}}) 
   1. The value of the interaction order. 
   1. the numerical value 
   1. {{{True}}}/{{{False}}}, specifying whether the parameter is complex ( {{{True}}}) or not ( {{{False}}}). 
   1. a string, giving a description of the parameter. 
=== !IParamList ===

{{{IParamList}}} is a list containing all internal parameter defined in the model file. Each parameter is represented by a four or six component list:
   * Is no {{{InteractionOrder}}} was defined for the parameter, then the length of the list is 4: 
   1. The {{{ParameterName}}} of the parameter. 
   1. The name of the {{{InteractionOrder}}} (usually {{{QED}}}/{{{QCD}}}) 
   1. The value of the interaction order. 
   1. the relation to other parametes (external and/or internal) 
   1. {{{True}}}/{{{False}}}, specifying whether the parameter is complex ( {{{True}}}) or not ( {{{False}}}). 
   1. a string, giving a description of the parameter. 
   * If an {{{InteractionOrder}}} was defined, then the length of the list is 6: 

   1. The {{{ParameterName}}} of the parameter. 
   1. the relation to other parametes (external and/or internal) 
   1. {{{True}}}/{{{False}}}, specifying whether the parameter is complex ( {{{True}}}) or not ( {{{False}}}). 
   1. a string, giving a description of the parameter. 
=== !ParamList ===

{{{ParamList}}} is a list containing both the external parameters.

Each external parameter corresponds to a six or eight component list. If no interaction order was defined
   1. The {{{ParameterName}}} of the parameter. 
   1. A tag {{{Ext}}}. 
   1. The numerical value 
   1. The LH block name. 
   1. {{{True}}}/{{{False}}}, specifying whether the parameter is complex ( {{{True}}}) or not ( {{{False}}}). 
   1. a string, giving a description of the parameter. 
 If an interaction order was defined 
   1. The {{{ParameterName}}} of the parameter. 
   1. A tag {{{Ext}}}. 
   1. The numerical value. 
   1. The LH block name. 
   1. The name of the {{{InteractionOrder}}} (usually {{{QED}}}/{{{QCD}}}) 
   1. The value of the interaction order. 
   1. {{{True}}}/{{{False}}}, specifying whether the parameter is complex ( {{{True}}}) or not ( {{{False}}}). 
   1. A string, giving a description of the parameter. 
 Each internal parameter corresponds to a five or seven eight component list. If no interaction order was defined 
   1. The {{{ParameterName}}} of the parameter. 
   1. A tag {{{Int}}}. 
   1. The relation to other parametes (external and/or internal). 
   1. {{{True}}}/{{{False}}}, specifying whether the parameter is complex ( {{{True}}}) or not ( {{{False}}}). 
   1. A string, giving a description of the parameter. If an interaction order was defined 
   1. The {{{ParameterName}}} of the parameter. 
   1. A tag {{{Int}}}. 
   1. The relation to other parametes (external and/or internal). 
   1. The name of the {{{InteractionOrder}}} (usually {{{QED}}}/{{{QCD}}}) 
   1. The value of the interaction order. 
   1. {{{True}}}/{{{False}}}, specifying whether the parameter is complex ( {{{True}}}) or not ( {{{False}}}). 
   1. A string, giving a description of the parameter.
