errormodule

#Error

##Description This unit contains the predefined subprograms that deal with errors returned from other predefined subprograms.

All routines in the Error unit are exported qualified (and thus must be prefaced with "Error.").

The constants representing the possible errors returned by this module can be found in the ErrorNum module.
