Rerrcode

Purpose
Get the last error code.
Synopsis
function Rerrcode:integer
Return value
0 if the last operations were executed successfully.
Example
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

Further information
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.
