When you submit a SAS program that calls an FEA (Financial Engineering Associates) function, the SAS session might end shortly after the SAS program has finished running and the SAS log might not contain any related warning or error messages.

The most likely cause for the session termination is that the SAS program does not call the FEA "uninit" function that is associated to the FEA library that the SAS program is calling. Several of the FEA libraries contain an uninit function. For example, the IntrLib library contains an Iuninit function. The purpose of the uninit function is to unbind the license from your FEA license server, which applies to you if you are using a license server for your FEA licenses instead of standalone license keys.

To prevent the session termination, ensure that you include a call to the associated FEA uninit function in your SAS program. In most cases, you only need to call the uninit function one time per project run for a given set of FEA function calls, and the uninit function call should be the final FEA function to be called. Another reason to minimize the number of calls to the uninit function is that it can be inefficient to call it many times.

Following are some sample steps to illustrate how you could call an FEA uninit function one time within a SAS® Risk Dimensions® analysis project.

1. Include a prototype of the uninit function in the PROC PROTO step. For example:
   proc proto ... ; ... void Efree_license (void); /* uninit function in FEA ErgLib library */ ... run;
   To find which uninit functions are available for which FEA libraries, and to determine what its prototype is, refer to the FEA documentation.



2. Define a method in PROC COMPILE that calls the uninit function. For example:
   proc compile ... ; ... method FEA_Efree_license kind=project; beginblock term; call Efree_license(); endblock; endmethod; ... run;
   The uninit function is not used for instrument valuation, so it is usually sufficient to include it in a project method instead of in a pricing method. Because the uninit function should only need to be called one time per analysis project run, it should suffice to include it in a term block within the method. An exception can be when a project is processed across multiple CPU's, in which case each spawned job should contain a call to the uninit function.



3. Ensure that the method containing the uninit function is configured in PROC RISK so that it gets called when the analysis project is run. For example:
   proc risk ... ; ... project Ergvals ... projectmethods=FEA_Efree_license ... ; runproject Ergvals ... ; ... run;
   The PROJECTMETHODS= option is used to specify which project methods to include when the analysis project is run. For more information about SAS Risk Dimensions, refer to the SAS Risk Dimensions documentation.
