Error description
If v5+ code is called from both pre-v5 and v5+ code, and the v5+ module is CANCELed and then called again, the legacy and v5+ run-time's control blocks may get out of sync, leading to a failure to initialize working-storage for the v5+ module. This occurs specifically if the v5+ module also requires the C/C++ run-time, which may be included due to use of the XML PARSE statement using the XMLPARSE(XMLSS) option. An IMS environment with CANCEL_PGM=Y may make this situation much more likely to occur.

Problem summary
**************************************************************** * USERS AFFECTED: Enterprise COBOL V5.1 and above users * * compiling and running programs that perform * * dynamic CALL and CANCEL in a mixed C/C++ * * and pre-V5+ COBOL rununit. * **************************************************************** * PROBLEM DESCRIPTION: Runtime ABEND0C4. When an Enterprise * * COBOL V5+ program is being dynamically * * called and canceled by both COBOL V5+ * * and pre-V5+ programs, the WORKING- * * STORAGE may not be initialized * * properly, which may lead to invalid * * storage access that can result in an * * 0C4 ABEND. * **************************************************************** * RECOMMENDATION: Apply the provided PTF. * **************************************************************** In a mixed C/C++, pre-V5+ and V5+ COBOL rununit, the COBOL dynamic call handler failed to correctly update the internal control blocks to reflect the state of the called program.
Problem conclusion
The COBOL dynamic call handler is corrected to update the internal control blocks properly.
