+SYNOPSIS
+ mixed * get_error_file(string name, int set_forget_flag)
+
+DESCRIPTION
+ Return information about the last error which occured for
+ <name> (where <name> is a valid name from the wiz list).
+
+ Result is an array of four elements: the filename of the
+ program where the error occured, the linenumber in the
+ program, the error message (runtime error messages usually
+ start with a '*'), and a numerical flag (the 'forget flag') if
+ the error information has been queried already.
+
+ If there is no error stored for the given <name>, 0 is
+ returned.
+
+ If <set_forget_flag> is non-zero, the 'forget' flag is set
+ for the error message after it has been returned.
