Feedback code parameter (fc)

The fc value is a feedback code that indicates the result of the math service. If you specify fc as an argument, feedback information in the form of a condition token is returned to the calling routine. The condition token indicates whether the routine completed successfully or whether a condition was encountered while the routine was running. If you do not specify fc as an argument and the requested service does not successfully complete, the condition is signaled. Math services call other services that might generate feedback codes.
