  10. RPG IV – V6R1 • Ability to run concurrently in multiple threads • Static (*Allthread) for fields • Serialize at the procedure level • Specify Main procedure to be called • No RPG Cycle is used • Local File support • Define files in a procedure after the ‘P’ Specification • Enhancements related to the use of files; • Qualified formats • LIKEFILE Keyword • New Template keyword • Passing files as parameters • EXTDESC to specify file to be used at compile time • Allow Data structure in the result field for EXTFMT • Significantly higher limits for the size of variables • Size of variables to 16MB from 64K • Number of elements in an array 16MB(16 million) from 32K • Length of string literals to 16MB from 32K • Relaxation of some UCS-2 rules (available starting in V5R3 through PTFs). • Miscellaneous enhancements • Reduce module size • Store parameter info in the program

  11. ILE RPG enhancements - threads Ability to run concurrently in multiple threads: • When THREAD(*CONCURRENT) is specified on the Control specification of a module • Multiple threads can run in the module at the same time. • By default, static variables will be defined so that each thread will have its own copy of the static variable. This makes them thread-safe. • Individual variables can be defined to be shared by all threads using STATIC(*ALLTHREAD). These variables are not thread-safe, by default. • D sharedFld S 10A STATIC(*ALLTHREAD) • A procedure can be serialized so that only one thread can run it at one time, by specifying SERIALIZE on the Procedure-Begin specification. • P serialProc B SERIALIZE

  12. Agenda • Ability to run concurrently in multiple threads • Static (*Allthread) for fields • Serialize at the procedure level • Specify Main procedure to be called • No RPG Cycle is used • Local File support • Define files in a procedure after the ‘P’ Specification • Enhancements related to the use of files; • Qualified formats • LIKEFILE Keyword • New Template keyword • Passing files as parameters • EXTDESC to specify file to be used at compile time • Allow Data structure in the result field for EXTFMT • Significantly higher limits for the size of variables • Size of variables to 16MB from 64K • Number of elements in an array 16MB(16 million) from 32K • Length of string literals to 16MB from 32K • Relaxation of some UCS-2 rules (available starting in V5R3 through PTFs). • Miscellaneous enhancements • Reduce module size • Store parameter info in the program

  13. ILE RPG enhancements – main without cycle Ability to define a main procedure which does not use the RPG cycle • MAIN keyword on the H specification designates one subprocedure as being the main procedure, that is, the procedure that gets control when the program gets called. • Other than being the program-entry procedure, the main subprocedure is like any other subprocedure. It does not use the RPG cycle. • The prototype for the main subprocedure must have the EXTPGM keyword; the main subprocedure can only be called by a program call. • H MAIN(ordEntry) • D ordEntry PR EXTPGM(‘W23OE14X’) • D parms … • P ordEntry B • D ordEntry PI • D parms … • ... • P E

  14. Agenda • Ability to run concurrently in multiple threads • Static (*Allthread) for fields • Serialize at the procedure level • Specify Main procedure to be called • No RPG Cycle is used • Local File support • Define files in a procedure after the ‘P’ Specification • Enhancements related to the use of files; • Qualified formats • LIKEFILE Keyword • New Template keyword • Passing files as parameters • EXTDESC to specify file to be used at compile time • Allow Data structure in the result field for EXTFMT • Significantly higher limits for the size of variables • Size of variables to 16MB from 64K • Number of elements in an array 16MB(16 million) from 32K • Length of string literals to 16MB from 32K • Relaxation of some UCS-2 rules (available starting in V5R3 through PTFs). • Miscellaneous enhancements • Reduce module size • Store parameter info in the program

  15. ILE RPG enhancements – local files Files defined in subprocedures • Local F specifications follow the Procedure-begin specification and precede the Definition specifications. • P writeRecs b • Foutfile o e disk • D data ds likerec(rec) • C write rec data • P writeRecs e • I/O to local files can only be done with data structures. There are no I and O specifications for local files. • By default, the storage associated with local files is automatic; the file is closed when the subprocedure returns normally or abnormally. • The STATIC keyword indicates that all invocations of the procedure will use the same open file. If the file is open when the procedure returns, it will remain open for the next call to the procedure.

  16. Agenda • Ability to run concurrently in multiple threads • Static (*Allthread) for fields • Serialize at the procedure level • Specify Main procedure to be called • No RPG Cycle is used • Local File support • Define files in a procedure after the ‘P’ Specification • Enhancements related to the use of files; • Qualified formats • LIKEFILE Keyword • Template keyword • Passing files as parameters • EXTDESC to specify file to be used at compile time • Allow Data structure in the result field for EXTFMT • Significantly higher limits for the size of variables • Size of variables to 16MB from 64K • Number of elements in an array 16MB(16 million) from 32K • Length of string literals to 16MB from 32K • Relaxation of some UCS-2 rules (available starting in V5R3 through PTFs). • Miscellaneous enhancements • Reduce module size • Store parameter info in the program

  17. ILE RPG enhancements – avoid compile-time overrides (F) EXTDESC keyword and EXTFILE(*EXTDESC) • EXTDESC keyword • Identifies the file to be used for an externally-described file (at compile time). • The filename is specified as a literal in one of the forms 'LIBNAME/FILENAME' or 'FILENAME'. • FoutputF o e disk extdesc(‘MYLIB/MYFILE’) • This removes the need to provide a compile-time override for the file. • EXTDESC can be used to solve the problem where a record format has the same name as the file. When EXTDESC is used to locate the file, then any name can be used as the RPG-internal name for the file. • The EXTFILE keyword is enhanced to allow the special value *EXTDESC, indicating that the file specified by EXTDESC is also to be used at runtime. • FoutputF o e disk extdesc(‘MYLIB/MYFILE’) • F extfile(*extdesc)

  18. Agenda • Ability to run concurrently in multiple threads • Static (*Allthread) for fields • Serialize at the procedure level • Specify Main procedure to be called • No RPG Cycle is used • Local File support • Define files in a procedure after the ‘P’ Specification • Enhancements related to the use of files; • Qualified formats • LIKEFILE Keyword • New Template keyword • Passing files as parameters • EXTDESC to specify file to be used at compile time • Allow Data structure in the result field for EXTFMT • Significantly higher limits for the size of variables • Size of variables to 16MB from 64K • Number of elements in an array 16MB(16 million) from 32K • Length of string literals to 16MB from 32K • Relaxation of some UCS-2 rules (available starting in V5R3 through PTFs). • Miscellaneous enhancements • Reduce module size • Store parameter info in the program

  19. ILE RPG enhancements – larger fields Larger limits for data structures, and character, UCS-2 and graphic variables: • Data structures can have a size up to 16,773,104. • Character definitions can have a length up to 16,773,104. (The limit is 4 less for variable length character definitions.) • The LEN keyword can be used instead of the Length entry to define the length of a variable or DS • UCS-2 and Graphic definitions can have a length up to 8,386,552 double-byte characters. (The limit is 2 less for variable length definitions.) • The VARYING keyword allows a parameter of either 2 or 4 indicating the number of bytes used to hold the length prefix. A parameter of 4 is required if the defined length is over 65535.

  20. ILE RPG enhancements - %ADDR for varying data %ADDR(varying_field : *DATA) • The %ADDR built-in function is enhanced to allow *DATA as the second parameter to obtain the address of the data part of a variable length field.

  21. Agenda • Ability to run concurrently in multiple threads • Static (*Allthread) for fields • Serialize at the procedure level • Specify Main procedure to be called • No RPG Cycle is used • Local File support • Define files in a procedure after the ‘P’ Specification • Enhancements related to the use of files; • Qualified formats • LIKEFILE Keyword • New Template keyword • Passing files as parameters • EXTDESC to specify file to be used at compile time • Allow Data structure in the result field for EXTFMT • Significantly higher limits for the size of variables • Size of variables to 16MB from 64K • Number of elements in an array 16MB(16 million) from 32K • Length of string literals to 16MB from 32K • Relaxation of some UCS-2 rules (available starting in V5R3 through PTFs). • Miscellaneous enhancements • Reduce module size • Store parameter info in the program

  22. ILE RPG enhancements – new UCS-2 rules Relaxation of some UCS-2 rules • The compiler will perform some implicit conversion between character, UCS-2 and graphic values, making it unnecessary to code %CHAR, %UCS2 or %GRAPH in many cases. This enhancement is also available through PTFs for V5R3 and V5R4. • Implicit conversion is now supported for • Assignment using EVAL and EVALR • Comparison operations in expressions and using fixed form operations IFxx, DOUxx, DOWxx, WHxx, CASxx, CABxx, COMP. • Note that implicit conversion was already supported for the conversion operations MOVE and MOVEL.

  23. Agenda • Ability to run concurrently in multiple threads • Static (*Allthread) for fields • Serialize at the procedure level • Specify Main procedure to be called • No RPG Cycle is used • Local File support • Define files in a procedure after the ‘P’ Specification • Enhancements related to the use of files; • Qualified formats • LIKEFILE Keyword • New Template keyword • Passing files as parameters • EXTDESC to specify file to be used at compile time • Allow Data structure in the result field for EXTFMT • Significantly higher limits for the size of variables • Size of variables to 16MB from 64K • Number of elements in an array 16MB(16 million) from 32K • Length of string literals to 16MB from 32K • Relaxation of some UCS-2 rules (available starting in V5R3 through PTFs). • Miscellaneous enhancements • Reduce module size • Store parameter info in the program

  24. ILE RPG enhancements – reduce module size Eliminate unused variables from the compiled object: • New values *UNREF and *NOUNREF are added to the OPTION keyword • For the CRTBNDRPG and CRTRPGMOD CMDs, and for the OPTION keyword on the Control specification. • The default is *UNREF. • *NOUNREF • Indicates that unreferenced variables should not be generated into the RPG module. • Reduces program size • If imported variables are not referenced, it can reduce the time taken to bind a module to a program or service program.

  48. Collaboration Challenges with Enterprise teams How can see the status of all of my teams in one place? Why are some teams not following our agreed upon process? How are our fellow teams in other platforms organized? Who is working on what? How can we verify that all of the components of an enterprise application have been built properly? Our enterprise development teams working on different platforms are struggling to communicate. How can we collaborate in the context of our work Why and when was this code change made? Low Complexity High Complexity We need to deploy an enterprise application to our System z, System i, and Unix servers. How can we coordinate that deployment? Distributed software development teams across the hall or spread around the world face similar challenges The build was broken by another team, how can our team repair w/o waiting
