The main program is protected with an ESTAE that retries for abends X'B37', X'D37', and X'E37' unless the two output data sets are full.

If the monitor abends, a software logrec is written for diagnostic information.

An FRR protects the data collection routine. If a problem happens, the FRR routine writes a record in the SYS1.LOGREC and flags the logical record header with the word ERRO.

If the ISPF application abends, the panel displays the ABEND code and the system takes a dump if the logon procedure contains a SYSUDUMP statement.
