Problem summary
**************************************************************** * USERS AFFECTED: Users of Enterprise COBOL 6.5 compiling * * programs with ARCH(11) that have loops * * copying data from one alphanumeric or * * alphabetic data item to another, one byte at * * a time, stopping either when the end of the * * sender or receiver is reached, whichever is * * shorter, or when a terminating character is * * found in the sender, and where the loop * * index is of type USAGE DISPLAY. * **************************************************************** * PROBLEM DESCRIPTION: Compiler abends with message * * MSGIGYCB7104-U Internal error while * * compiling program P310106A. Failed * * assertion on /c390/jenkins/continuous * * /workspace/e2e.compiler.build_build_cob * * _6.5/builds/cob/6.5/tr.v65.cobol-prod- * * opt/tr.source/ibm/il/IlOps.hpp:1354. * * Compilation terminated. * **************************************************************** * RECOMMENDATION: Apply the provided PTF * **************************************************************** The optimizer can generate an efficient instruction sequence when copying data between alphabetic or alphanumeric data items, stopping when the end of the shorter data item is reached or when a terminating character is found in the sender. The optimizer did not allow a USAGE DISPLAY data item as a loop counter in this sequence, but rather than avoiding the sequence, the optimizer attempted to generate the sequence and then terminated when the unexpected USAGE DISPLAY data item was found.
Problem conclusion
The compiler has been fixed to allow USAGE DISPLAY loop counters when optimizing the copying of data between alphabetic or alphanumeric data items.
