Error description
Customer complained the 0C4 abend: CSQ1,ABN=0C4-00000004,U=BJS0062 ,C=W9700.800.DB2 -CSQ5SCST,M=CSQGFRCV,LOC=CSQ5LPLM.CSQ5SCST+00000B70 From the doc we can see that the problem is caused when an SQL error (-904) occurs during a DISPLAY CHSTATUS command. This error should be passed back up the calling stack to be handled, but in this case the calling module has not passed in a suitable parameter to return the SQL RC, and the attempt to store the value fails with an S0C4-4 abend.
