11.2.3 Error messages in checkback signals
Overview
Operator/travel errors [BF/FS] and data errors/machine data errors/traversing pro-
gram errors [DF], are communicated to the user by way of checkback signals (call
of the POS_CTRL block) and operating errors by means of diagnostic interrupts
(see Section 6.3.4). The error-specification is stored in the form of an error number
(see error list in Table 11-6...11-8).
