APAR status
Closed as program error.
Error description
File related structures set up and code generated by the compiler for an LP(64) program are incorrect leading to the structures only being initialized correctly the first time the program is called. This can lead to various problems at runtime, such as abend SC03. This does not affect LP(32) programs.
Local fix
In some contexts, the file use can be isolated in a separate module that's entered only once.
Problem summary
**************************************************************** * USERS AFFECTED: Users of Enterprise COBOL 6.4 compiling and * * running programs with the LP(64) option in * * effect where the programs contain file I/O * * operations and are also called more than * * once during the life of a run unit. * **************************************************************** * PROBLEM DESCRIPTION: Runtime abend (typically SC03 or S0C4) * **************************************************************** * RECOMMENDATION: Apply the IBM-provided PTF * **************************************************************** Programs compiled with the LP(64) option require special handling of the static initialization of various runtime-managed file control block fields due to the fact that in such programs the fields do not reside in the Writable Static Area (WSA), as in programs compiled with the LP(32) option in effect. In some cases, these initializations were being incorrectly performed multiple times when a program is called multiple times during the life of the run unit.
Problem conclusion
The compiler was updated to fix the problem of repeated static initialization of file control block fields in programs compiled with the LP(64) option in effect.
