Get the last error code.

0 if the last operations were executed successfully.

The following example prints an error message in case of errors in R evaluations:

 Reval('missingfunction()')
 if Rerrcode<>0 then
  writeln('Something went wrong: ', Rerrmsg)
  Rclearerr
 end-if

The Rerrcode is set to non-zero values in case of errors, but not cleared after successful operations, so it is possible to check it after several operations to verify that all executed without errors. To clear it, use function Rclearerr.

Rclearerr, Rerrmsg.
