34  ** Parameters:
35  ** Error error number which is to be trapped
36  ** Message pointer to a string to be printed as an error message
37  ** Globals:
38  ** ErrorTrapStack stack of error traps
39  ** CurrentTrapDepth number of traps on the stack
40  ** Operation:
41  ** This routine prints the specified error message to stderr.
42  ** It then jumps to the current error trap. If the error trap
43  ** stack is empty, the calling program is terminated with a
44  ** fatal error message.
45  ** Return:
46  ** None - this routine does not return.
47  ** Exceptions:
48  ** Empty error trap stack terminates the calling program.
