Futurebasic/Language/Reference/syserror statement

SYSERROR Syntax SYSERROR = OSErrorCode% Description This statement sets the value of FutureBasic's internal SYSERROR variable. FB sets this variable automatically when you perform disk file operations. The SYSERROR statement can be used to reset the variable to zero after one of these other operations has set it to a nonzero value. In virtually every case, you will use _noErr (0) as the OSErrorCode% parameter. Note The internal SYSERROR variable does not behave like an ordinary variable. For example, you cannot set its value by means of an INPUT or READ statement. See Also SYSERROR function; ERROR function; ON ERROR
