In the data area data structure, letter "U" must be entered to define the data structure as a data area data structure. * File information data structure A file information data structure provides exception/error information that may be occurred when processing a file during program execution. This type of data structure contains pre defined sub fields that identify * The name of the file for which the error occurred * The record processed when the error occurred * The operation being processed when the error occurred * The status code number * The RPG/400 routine in which the error occurred. Exception errors may be controlled by testing for an error code in the *STATUS field which is included in a file information data structure. Specifically, keywords including *FILE, *RECORD, *OPCODE, *STATUS, *ROUTINE provide the previously named information. * Program status data structure Program status data structure however identity exception/errors that are generated in the program by RPG/400 operations and not by a file. Note that any code greater than 00099 is flagged as an exception/error. Four keywords - *STATUS, *ROUTINE, *PROGRAM, *PARMS are supported by a program status data structure. 40.

MOVEA: - Transfers valued from Factor2 to the Result field of the Operation but one of them must be an array 273. Advantages of ILE or RPG? 1) In RPG it is one step compilation (we will get *PGM object) while in ILE-RPG it is two step compilation (we have to create a *MODULE and then bind that module to a program. In RPG we cannot call a program i.e. recursive call is not supported. While in ILE RPG it is supported. Extended Factor 2 Length of Factor 1 & 2 is increased to 14 as well as Length of OP-CODE is 10 Free format is allowed Built-in-functions are available. Frequently Asked Questions in AS/400 Page 21

In case of ILE we have the concept of ACTIVATION GROUP. In ILE EPM (Extended Program Model) is implemented while in RPG OPM (original program model) 274. What is sub-file? It is group of records read from or written to display file in a column format. It is always a subset of records from physical file hence the name subfile. 275. SFL and SFLCTL ? There are the two mandatory key words for subfile program /design. While SFL is used to define Subfile record format while SFLCTL is used to define Subfile Control Record format. And this two are the different parts of sub-file. 276. What are the Sub file Types? There are three types of sub file Load All - In which all the records from the Physical file or at max. 9999 records are written to subfile. Here sub file size should 9999 or the number of records form PF which ever is less. In this case PAGEUP AND PAGEDOWN is taken care by system. SFLPAG should be less than SFLSIZ Single Page/non-elastic – In this case sub file size (SFLSIZ) must be equal to sub file page (SFLPAG). For example, if SFLSIZ = 10 and SFLPAG = 10, then 10 records from file are written to subfile. In this case PAG Expandable/elastic/growing – In this case SFLSIZ should be grater at least by 1 than SFLPAG.(this is applicable to Load all type also). For example, SFLSIZ = 10 and SFLPAG=9, then 10 records from written the sub file from physical file but only 9 are displayed on screen. 277. what is SFLDROP and SFLFOLD These are the two key-words used in sub-file for displaying additional information which cannot fit one line. SFLFOLD will give view in folded form and SFLDROP will give view in truncated form. 278. What is SFLCSRRRN and SFLRCDNBR ? SFLCSRRRN will give the RRN of the record where the cursor is positioned. SFLRCDNBR will give the RRN of the First record displayed on the screen at a given time. 279. What is SFLNXTCHG? Whenever a record is changed on display file. An MDT is set ON. If an indicator is associated with SLFNXTCHG and it is SETON then READC will read only the changed record. And if the indicator is not associated and it is seton it READC reads all the records from sub-file 280. Reading records from a subfile using READC With the help of READC op-code we can read only changed records from subfile.

281. Required key words for subfile. SFL, SFLCTL, SFLDSP, SFLSIZ, SFLPAG are the mandatory key words. SFLDSPCTL, SFLCLR, SFLINZ, SFLEND are the optional key words used in subfile. 282. PLIST and KLIST PLIST is a list of parameter and KLIST is the list of KEY fields. Frequently Asked Questions in AS/400

Page 22

283. Position to particular record? With help of op-code SETLL from RPG/RPGLE, it will position the record pointer just before the required record. Next READ will read that particular record. 284. LR indicator and RETURN operation? LR indicator – It close all the open files, Frees the space and release ODP. RETURN – It dose not close files and dose not release the ODP and passes the control to the calling program / command prompt if the program is called from command prompt. 285. Different operations on indicator? There are only two operations on indicator those are SETON and SETOFF. 286. What is the operation / op-code to change in file? In RPG/RPGLE with the help of UPDAT / UPDATE op-code. 287. How do I insert a record into a database file? In RPG / RPGLE with the help of WRITE op-code. In CL/CLLE we can not insert a record into database file. 288. Two way of deleting records from file? one is DELETE and other with the help of O-Specs ADD/DEL specify DEL. 289. How to define a subroutine ? with help of two op-code BEGSR(Begin subroutine) ENDSR (End subroutine) and between these two op-codes write the instruction. The whole construct is defined as subroutine. 290. In case of Load all sub-file, if we type options and then PGDN,PGUP , will options be there on the display / in subfile. Yes. It will retain all the options entered in the previous page. 291. How will you take care of multiple options in case sub-file? We will have to handle it within the program using a READC in a loop. 292. If we type some options on screen out of which some are invalid and pressed enter, what should happen? It should process all the valid options before invalid options encounter. Once invalid options is encountered program should stop processing and display error message at the bottom of the scrreen. 293. How will you achieve POSITION TO in Load all subfile? While loading subfile move RRN, KEYVALUE in to a two dimensional array. When a key value is entered into POSITION TO field, having a LOOKUP into a array we can get a corresponding RRN. Assigning RRN value to SFLRCDNBR and then displaying the sub-file. 294. Types of Data Structures? a. b. c. d. e.

File Information Data Structure. Program Status Data Structure. User Defined Data Structure. Multiple Occurrence Data Structure. Date Area Data Structure.

What is the disadvantage of using Global variable? We can not trace out at which point the value of variable is changed. 309. What is Service Program?

Frequently Asked Questions in AS/400

Page 25

A Service Program is a collection of runnable procedures and available data items easily accessible by other ILE programs. In many respects it is similar to a subroutine library and procedure library. A service program differs from a program in two ways: It does not contain a program entry procedure. This means that you cannot call a service program using the CALL operation. A service program is bound into a program or other service programs using binding by reference. 310. What is *ISO date format? YYYY-MM-DD for other formats refer to IBM manual or ERIS document. 311. If we tried to move year part of *ISO date into a field of length 3, what will happen ? Program crashes, as in case of *ISO format it required fields of 4,2,2. 312. How to avoid using indicators in ILE ? By using the standard Built In Expressions like %FOUND,%EOF, NOT %EOF, %BOF, NOT %BOF…etc. 313. What is difference between module and program ? Module is a non-runnable object where as program is runnable. 314. What is difference between ILE RPG and RPG/400 ? Difference is in program development (specification), program creation (create module, bind module to create program), program running (activation group, resource sharing). 315. What are different types of Arrays and what is the difference between them ? There are 3 types of arrays Compile time, Pre-Run time and Run time. Compile time array gets value at the time of compilation of the source of a program. Pre-run time array gets value from a file at the beginning of a program execution (before any statement of a program is executed). Run time array gets value during the program execution. 316. What is Multi occurence data structure ? It is an array of a Data structure. 317. Can an indexed file (File with key fields) be accessed in arrival sequence in an RPG program ? Yes, don't specify "K" in F specification in the program for this file. 318. What is the difference between *LIKE and *NAMVAR opcode? *LIKE defines program variable same as that of another pre defined variable. *NAMVAR is used to define variable as Data area. 319. How to handle run time error in RPG Program ? by using indicator on statement, subroutine *PSSR 320. How will you display a particular page (or record) in a Sub file? Move a valid relative record number(RRN) in the field specified using SFLRCDNBR keyword in DDS 321. What is difference between Command Function and Command Attention key? Frequently Asked Questions in AS/400

Page 26

Command function key returns variable value along with response indicator (associated with CF key) where as Command attention returns only the response indicator value. 322. What are different type of Sub files ? There are three types of Subfile (1) Load all Subfile (Page Size = 9999) (2) Extendable Sub file (Sub file size > Sub file page), (3) Load by Page (Sub file size = Sub file page) 323. What is SFLNXTCHG keyword used for ? To read the change records for 2nd, 3rd,...times from sub file after reading them once. 324. What is SFLROLVAL keyword used for ? It specify the number of records to roll in a subfile. 325. What is difference between keyword SFLCSRRRN & RTNCSRLOC ? RTNCSRLOC returns the location of cursor into the variable (associated with this keyword) and SFLCSRRRN returns the relative record number where the cursor is positioned.

326. What's the difference between CHAIN and SETLL? Is there a performance advantage? There are two important differences between CHAIN and SETLL. 1. The CHAIN operation applies a record lock to files that are open or update. The SETLL operation does not apply the lock. 2. The CHAIN operation copies the record's data to the input buffer for the program. The SETLL operation does not.

Syntax: All non-external data definitions can now be specified in a D-specifications that are new to ILE RPG. In addition you can define "named constants" that greatly simplify coding in the Cspec's. Also C-spec formats have changed slightly to provide for variable names of up to 10 characters (up from 6 in RPG/400) and longer operation codes. New Operations: Several have been added. One that I like is EVAL which allows you to evaluate a mathematical expression similar to Cobol and other mathematical programming languages such as Basic, FORTRAN, PL/1, etc. Modularity: This is a big plus. You can now write modules (non-executable) in several languages and bind them together into a single ILE program. Thus you can use the best language (ILE C, ILE Cobol, ILE RPG, ILE CLP) for a process or use existing modules to write a program. You can also write callable procedures or procedures that function like built-in functions. More: There is of course much more that is new in ILE RPG. For performance reasons, you should have a good understanding of ILE. Bryan Meyers has written several very good articles in NEWS/400 that can help you avoid some ILE traps. He is also one of the moderator |

PCVTSAVPF AS/400 Command Introduction The PCVTSAVPF and PCVTPFSAV commands together provide a simple low-level way of transferring all types of objects between two ISeries (AS/400, AS400) systems using intermediate save files and physical files. This is one of the commands in our ISeries utilities library (click this URL for full contact and pricing details). This assumes the following steps: Frequently Asked Questions in AS/400

1) Save object(s) on 1st ISeries to save file using SAVOBJ command 2) Convert save file to physical file also on 1st ISeries using PCVTSAVPF command 3) Transmit the physical file to a 2nd ISeries e.g. via DDM or FTP 4) Convert the physical file on the 2nd ISeries back to a save file using the PCVTPFSAV command 5) Restore the object(s) from the save file onto the 2nd ISeries using the RSTOBJ command

Examples PCVTSAVPF FROMFILE(TFRLIB/TFRSAV1) TOFILE(TFRLIB/TFRPF1) MBR(*FIRST) Command above converts the contents of the save file TFRSAV1 in library TFRLIB to a physical file TFRPF1 in the same library.

Restrictions 1) The physical file must have a record length of exactly 528 bytes if the corresponding PCVTPFSAV command is to process correctly. In other words, use the CRTPF command with a RCDLEN(528) parameter to create the TOFILE physical file for the PCVTSAVPF command.

IBM rebranded the AS/400 - some users called it AS400 - to ISeries several years ago. All 3 names - ISeries, AS/400, AS400 refer to exactly the same system.
