Error description
Problem similar to the one described in PK83174. However in this case the command is a CEMT SET TSQ(*) DELETE, which results in a true SET, which then results in an attempt to overwrite ERDSA and an Abend0c4. The S0C4 occurns when invalid values cause module DFHEMT56(UK49670) +X'1832' to overwrite the ERDSA storage. Additional Keywords: 1832, DFHEMT56, PK83174, 83174, DELETE, ERDSA

Problem summary
**************************************************************** * USERS AFFECTED: All. * **************************************************************** * PROBLEM DESCRIPTION: CEMT S TSQ(*) DELETE results in an * * abend0C4 in DFHEMT56. * **************************************************************** * RECOMMENDATION: * **************************************************************** An attempt to delete more than 32767 tsqueues using CEMT SET TSQUEUE(*) DELETE results in a storage violation. This is because a multiply halfword instruction in DFHEMT56 causes a large negative value to be used as an offset into storage, and so an attempt is made to write into ERDSA. Additional Keywords: DFHEIN56
Problem conclusion
DFHEMT56 has been changed to limit the number of elements being set for CEMT SET TSQUEUE to 32766. If the number of elements is greater than or equal to 32767, a "too many elements" message is displayed and no tsqueues will be deleted by the SET request.
