Problem summary
**************************************************************** * USERS AFFECTED: Users of Enterprise COBOL V5 and later * * releases compiling and running COBOL * * programs that use overlapping MOVE to * * initialize alphanumeric or group identifier. * * * **************************************************************** * PROBLEM DESCRIPTION: MOVE statements of the form below can * * be inefficient. * * * * 01 A PIC X(1000000). * * * * MOVE ' ' to A(1:1). * * MOVE A TO A(2:999999). * * * * The overlapping sending and receiving * * fields in the second MOVE statement * * can restrict the generated code * * sequences used by the compiler. * * * **************************************************************** * RECOMMENDATION: Apply the provided PTF. * * * **************************************************************** MOVE with overlapping sending and receiving fields can be inefficient as the overlapping data can restrict the generated code sequences used by the compiler.

Problem conclusion
Special processing has been put in to handle the MOVE statement described the Problem Description. In general COBOL programs should avoid using overlapping MOVE statements in order to get benefits from COBOL compiler optimizations.
