Local fix
Problem summary
**************************************************************** * USERS AFFECTED: Users of Enterprise COBOL 6.1 compiling and * * running programs that are large or compiled * * with OPT(0) and contain an INITIALIZE * * statement that is used to initialize a * * table. * * * **************************************************************** * PROBLEM DESCRIPTION: Runtime performance of the program is * * slower compared to an equivalent * * program compiled with the Enterprise * * COBOL V4.2 or earlier compiler. * * * **************************************************************** * RECOMMENDATION: Apply the provided PTF. * * * **************************************************************** With large programs and programs compiled without optimization, the compiler did not have the necessary infrastructure to fully optimize table initialization operations.
Problem conclusion
The compiler was updated to include support for optimizing INITIALIZE statements on tables at all OPT levels and even on large programs as long as the tables do not include any elementary items that are excluded from the initialization (e.g., filler, pointer, and index data items, which are excluded by default, and data items excluded due to the use of INITIALIZE phrases such as REPLACING).
