C\ Beginning of mainline

C\

C\ Remove an exit program from the exit point and then dere￿gister

C\ the exit point. It is not necessary to remove exit programs

C\ from an exit point before deregistering the exit point. It is

C\ done here only for illustrative purposes.

C\

C\ Initialize the error code parameter. To signal exceptions to

C\ this program by the API, you need to set the bytes provide￿d

C\ field of the error code to zero. Because this program has

C\ exceptions sent back through the error code parameter, i￿t sets

C\ the bytes provided field to the number of bytes it gives￿ the

C\ API for the parameter.
