A.1 Error/Event Parameter Identification Codes
Table A-1 lists the identification codes that the ACL might report in the Error/Event Log data
returned for aclGetErrorLog() and acl_errlog_library. For some of these codes, additional
integer values are included to further describe the condition detected. In many cases, this
additional information is intended for Ampex factory personnel as interpretation of integer
values requires a detailed understanding of ACL internal operation.
