Do I have to use the error routine to trap the error, or is there a more direct way to check for the error here?

The simplest method is using ON ERROR command.
ln_Error = 0
On error ln_Error = error()
owsh=CreateObject("Scripting.FilesystemObject")
On error
If (ln_Error != 0)
   Wait 'Error = ' + transform(ln_Error)
else
   * Continue
endif
