100 A duplicate key was detected where duplicates are not allowed.
102 This indicates that a routine was called with an illegal parameter. For example, specifying a key number that is larger than the number of keys in the file would result in this error.
104 An attempt was made to open more files than the system allows open at once.
105 The index file is corrupt or the physical disk file does not match the type of file being opened. If the index file is corrupt, it should be reconstructed using the appropriate host system utility.
107 The requested record is locked by another process or (for some systems) by another file handle used by this process.
111 The requested record was not found.
112 The current key of reference was in the "undefined" state when the "i_next" or "i_previous" routines were called. There is no current record from which to read forwards or backwards.
113 The file is locked against the current open mode.
116 The system ran out of dynamic memory.
117 An operation was requested that the current open mode doesn't allow. For example, attempting to add a record to a file that is open for input-only results in this error.
126 The requested operation is not supported by this host system.
127 The disk became full while adding a new record.
128 The size of the new record doesn't match the type of file being opened.
129 The system ran out of lock-table entries.
130 The file is missing.
131 Invalid permission for the operation.
