*Real()

Creates a real entity.

Syntax

*Real(real_name,"real_label",edit_option)

Arguments

real_name: The variable name of the real entity.; Data type: varname
real_label: The descriptive label of the real entity.; Data type: label
edit_option: A keyword which specifies whether or not this data member entity is editable in the MotionView graphical user interface. Valid values are: EDIT or NO_EDIT; Data type: keyword

Example

*DefineDataSet(dsdef_vehpar)
 *String(model,        "Model")
 *Integer(wheelbase,   "Wheelbase")
 
*Real(spr_mass_cg_hgt, "Sprung Mass CG Height", EDIT)
 *Real(frnt_spr_mass,  "Front Sprung Mass", NO_EDIT)
 *Real(rear_spr_mass,  "Rear Sprung Mass", EDIT)
*EndDefine()
*DataSet(ds_vehpar,    "Vehicle Arguments", dsdef_vehpar)
*SetString(ds_vehpar.model, "Sport Utility")
*SetInteger(ds_vehpar.wheelbase,     3000) 
*SetReal(ds_vehpar.spr_mass_cg_hgt,  800.0)
*SetReal(ds_vehpar.frnt_spr_mass,    800.0)
*SetReal(ds_vehpar.rear_spr_mass,    600.0)

Context

Properties

Table 1.

varname	string	The variable name of the real entity.

Comments

A real entity is an entity that holds a real scalar.

Real entities may be created in dataset or table record definitions.

Variables created in *Real() statements are assigned values in *SetReal() statements.

When *Real() statements are used in a *DefineSystem(), *DefineAnalysis(), or *BeginMDL() block, the real entity is created inside an implicitly created dataset with the variable name "Ds_Variable". These real entities are then accessed from this dataset variable name when needed, for example,

*DefineSystem(def_sys ) 
  *Real(real_name, "Real variable", EDIT) 
  *SetReal(Ds_Variable.real_name, 100)
*EndDefine()
