To modify an existing simplified representation, retrieve it, then get the handle to its
ProSimprepdata structure by calling the function
ProSimprepdataGet(). (If you created the representation programmatically within the same application, the
ProSimprepdata handle is already available.) After modifying the data structure, reassign it to the corresponding simplified representation by calling the function
ProSimprepdataSet(). Use the function
ProSimprepdataTmpvalSet to specify whether the newly created representation is temporary. Pass the value
PRO_B_TRUE to the input argument
temp to make the newly created representation a temporary representation.
