BKERROR
In another example, BKERROR is called to retrieve the message corresponding to the MPE
file system error code returned when the first character of status is 9.
10 DIM S$(4),M$(72)
.
.
.
50 IF S$(1;1)="9" THEN DO
60 CALL BKERROR(S$,M$)
70 PRINT"FILE ERROR";S$(2);"MEANS";M$
80 DOEND
Suppose the value returned in
status is 9172. The routine above prints the following
message when the program is run:
FILE ERROR 172 MEANS KEY NOT FOUND; NO SUCH KEY VALUE
