YES, WHATEVER the STATEMENTS SPECIFIED are EXECUTED.

Yes, Whatever the statements specified are executed.

WHENEVER an exception/error OCCURS and *PSSR is DECLARED in F-specs, it is automatically goes to PSSR.

Whenever an exception/error occurs and *PSSR is declared in F-specs, it is automatically goes to PSSR.

While loading SUBFILE move RRN, KEY VALUE into a two DIMENSIONAL ARRAY. When a key value is entered into POSITION TO field, having a LOOKUP into an array we can get a corresponding RRN. ASSIGNING RRN value to SFLRCDNBR and then displaying the sub-file.

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 screen.

We will have to HANDLE it within the PROGRAM USING a READC in a LOOP.

• In RPG / RPGLE with the help of WRITE op-code.
• In CL/CLLE we can not INSERT a record into DATABASE FILE.

There are only TWO OPERATIONS on INDICATOR those are SETON and SETOFF.

There are only two operations on indicator those are SETON and SETOFF.

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.

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.

PLIST is a LIST of parameter and KLIST is the list of KEY fields.

SFL, SFLCTL, SFLDSP, SFLSIZ, SFLPAG are the MANDATORY KEY words. SFLDSPCTL, SFLCLR, SFLINZ, SFLEND are the OPTIONAL key words used in subfile.

SFL, SFLCTL, SFLDSP, SFLSIZ, SFLPAG are the mandatory key words. SFLDSPCTL, SFLCLR, SFLINZ, SFLEND are the optional key words used in subfile.

With the HELP of READC opcode we can read only CHANGED RECORDS from SUBFILE.

With the help of READC opcode we can read only changed records from subfile.

Whenever a record is changed on display file. An MDT is set ON. If an INDICATOR is ASSOCIATED with SFLNXTCHG 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

• 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.

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.

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.

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.

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.

• 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 ILERPG 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.
• 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)
