CICS loops are categorized as one of 3 types - tight loops, non-yielding loops or yielding loops. Of those 3 types only the yielding loops cannot be detected by CICS because they contain EXEC CICS commands which give control back to the CICS dispatcher and therefore reset the cpu timer for that task. Both tight loops and non-yielding loops will be detected by CICS and will abend with an AICA if the ICVR parameter is set to a positive value.
