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.
