  • Indicator data structure for display file indicators > 99 ...

    To avoid the use of numeric indicators in RPGLE, we created an indicator data structure for display file indicators. We do not make use of the INDDS keyword that lets you associate a data structure name with the INDARA indicators for a workstation file. Then the length of the indicator data structure would always be 99. Re: Based data structure as dynamic array -- allocate just 2004 any and build use and If destroy list

Most RPG programmers would probably choose to call the IBM *API to Retrieve Network Attributes (QWCRNETA).

    I believe I did something like that at my former employers. But they really hated dynamic SQL for frequent run or interactive stuff - it used to hog resources building the access each time, and they had a seriously in need of rewrite order entry process that was a system hog also - that 90% of the system users were using at any given time. Data structure is specified in the Input Specification of an RPG 3 Program where as in RPG 1V we specified in 'D' specification. Data Structure is define an area in storage and layout related subfields. There are 4 types of data structures 1) Data Area Data Structure 2) File Information Data Structure 3) Program Status Data Structure

    RPG IV Free-Format Data Area Data Structures

    To define the local data area in a data structure in free-format, there are two methods available, just as there was in fixed-format. The first method automatically reads the information from the LDA into the RPG data structure during the program load initialization phase, and then it writes the data structure data back to the LDA at program close. wat is the difference between array and multiple occurence data structure?

The thing to remember is you can assign long names without affecting anything existing as long as you leave the short system names alone; so no level checks for existing programs. Then in your RPG program, simply add the ALIAS keyword to your F-Spec and instead of pulling in the short names, the compiler will use the long names.

    Program Status Data Structure - MidrangeWiki

    * Program Status Data Structure D SDS List the sub-fields you need below that. They're described in the ILE RPG language reference. Declaring an externally described data structure allows you to use any of the information in the program status data structure without worrying about sub-field locations. Also, a data structure helps enforce data types in memory. Numeric fields from files are brought into RPG programs and stored in program memory implicitly as packed-decimal values, regardless of the data type in the database. If the data type format is important, you can use the DS to enforce it. Thanks to the guys who helped me out in the previous topic with constructors...I think I've got a decent namespace down for a basic rpg but was looking for some feedback. Here's the code. I'm wondering if it's okay to write it like this. The idea is that characters have these things called guardians which are like summons in final fantasy.

I emailed my code to the patron saint of RPG programmers, Barbara Morris, of the RPG compiler development team at IBM Toronto. She had a better idea. (Of course.) Barbara moved the two data structures into subfields of a qualified data structure and used OVERLAY to place the output format on top of the input format. In we can pass DS as a parameter by 2 methods in RPG IV.

Print . Over the last few years we've seen massive changes in the RPG language. Subprocedures and prototyping opened new methods of modularizing and calling our code. Note: If you don’t like testing with indicators, try using the INDDS keyword which lets you associate a data structure name with the INDARA indicators for a workstation or printer file. This data structure contains the conditioning and response indicators passed to and from data management for the file, and is called an indicator data structure.

    Data Structures - IBM

    The ILE RPG compiler allows you to define an area in storage and the layout of the fields, called subfields, within the area. This area in storage is called a data structure.. You define a data structure in free form by specifying the DCL-DS operation code followed by the data structure name and keywords. When you use UDS in columns 23-25 to define a data area data structure, the RPG program will read and lock the data area automatically when the program starts, then upate and lock it when the program ends. You can use the IN, OUT, and UNLOCK operations to specify additional operations, but the data area will be locked when the program begins: What I had hoped to do was a) define an externally-described data structure, based on the file that I'm using, and then b) define a field in the data structure that will be my returned record set using the LIKEDS keyword and referencing the externally-defined data structure. My code looks like this:

    These enhancements to RPG III were not available in the System/38 version of RPG III. RPG IV. RPG IV, a.k.a. RPGLE or ILE RPG,) was released in 1994 as part of the v3r2 release of OS/400. With the release of RPG IV, the RPG name was officially no longer an initialism. RPG IV offered a greater variety of expressions within its Extended Factor-2 ... Essentially, all data structures work in the same way - You create a data structure and store its index value in a variable. You then use this index to reference the data structure in all further function calls that can perform operations on it. Finally, once you are done you destroy the data structure again to remove it from memory.

    Externally described Data Structures @ RPGPGM.COM

    Why an externally described structure rather than a copy member, which is how I bring in the program data structure? An external structure does have language independence, which makes it useful if you want to bring in a data structure of system value in COBOL and RPG, and it is great for using with IO, and it is easy to bring in the same thing several times if you need to. When OS/400 V5R1 was announced, it included what I would consider the most significant enhancement to RPG IV data structure support in history, qualified names. Qualified data structure names allow you to refer to the subfields of a data structure by qualifying them to the data structure name itself. In V5R2, IBM provided additional functionality that let RPG IV program-mers use key arguments within a free-format Chain or Setxx operation or use the %Kds built-in function with a data structure. These enhancements represented a big step forward in “de-clunking” the calculations.
