12© Copyright IBM Corporation 2014



How do you access IBM i Information ?

13

Past– Write code to call

– CL Commands – System APIs

– Write more code to sort, filter, find what you are after

Today with SQL Services

– With a single SQL statement

– Retrieve information

– Leveraging the power of SQL

– Sort, Filter, find what you are after



Built in SQL Services – Use SQL to get info from the system!

14© 2014 International Business Machines Corporation

SELECT * from qsys2.user_info where status = '*ENABLED' AND

DATE_PASSWORD_EXPIRES BETWEEN CURRENT TIMESTAMP AND CURRENT TIMESTAMP + 7

DAYS;

SELECT USER_NAME, SUM(STORAGE_USED) AS TOTAL_STORAGE_USED from

qsys2.user_storage

GROUP BY USER_NAME ORDER BY TOTAL_STORAGE_USED DESC FETCH FIRST 10 ROWS

ONLY ;

Find who is using the most

storage!

Who’s password is about to expire

Modern RPG – Constant Transformation

23



RPG IV - A Modern Business Language

Primary goals for RPG IV

– Interoperability

o Java

o XML

o SQL

– Readability

o Free form

o Blank lines

o Comments

– Functionality

o Procedures

o Data areas

o Data structures

o More data types

o Extended file support

– Modern Tools

o RD i, RTC, ARCAD Power Pack

read file; // Get next record

dow not %eof(file); // Keep looping with record

if %error;

dsply ‘The read failed’;

leave;

else;

chain(n) name database data;

time = hours * num_employees

+ overtime_saved;

pos = %scan (‘,’ : name);

name = %xlate(upper : lower : name);

exsr handle_record;

read file;

endif;

enddo;

begsr handle_record;

eval(h) time = time + total_hours_array (empno);

temp_hours = total_hours - excess_hours;

record_transaction();

endsr;

Free format C specs



25

Full Free Form RPGctl-opt bnddir('ACCRCV');

dcl-f custfile usage(*update);

dcl-ds custDs;

dcl-f report printer;

read custfile custDs;

dow not %eof;

if dueDate > %date(); // overdue?

sendOverdueNotice ();

write reportFmt;

exec sql insert :name, :duedate into

mylib/myfile;

endif;

read custfile custDs;

enddo;

inlr = '1';

dcl-proc sendOverdueNotice;

/copy invoices

sendInvoice (custDs : IS_OVERDUE);

end-proc;

No /FREE, /END-FREE

All free-form statements

Better colorization options

in the editor



Calc Specs get out of jail

• In 9.0.1 we no longer need /free

directives

• The styling of the text is now

token-based rather than

operand-based.

• Highlighting of literals, BIFs,

control op-codes

Bracketed by /free and /end-

free directives

Calcs begin with opcode and

end with semicolon



Today H, F, D and P specs are free too!



Remove 8-80 Column Restriction Today column 1-8 are reserved (goes back to the punch card days)

Max Column for content is 80 (again….punch card)

• If column 1 of a source line contains '**FREE', the following lines contain free-

form RPG code beginning in column 1 and continuing to the end of the line

• If **FREE has not appeared in the source file, or if column 1 of a source line

contains **END-FREE, the following lines have RPG code in columns 6 - 80. If

columns 6 and 7 are blank, the code is free-form.



RPG• Modern coding style

– Easier to code and maintain

– Easier for new programmers

• But older code still works• Easily express business logic

– Fully-integrated decimal arithmetic

– Powerful set of built-in functions for string processing

– Use either native I/O operations or embedded SQL

V5R3

%SUBARR

Sort and search partial arrays

%DEC(date)

%TRIM specific characters

Trim a passed parameter

63-digit support

Data structure I/O for more operations

Preprocessor to handle /IF for CRTSQLRPGI

Implicit conversion for UCS-2 for EVAL and IF

7.1

Free-form H, F, D and C statements

Removal of 8-80 column limit

Sort and search data structure arrays

Sort ascending or descending

%SCANRPL built-in function

Support for ALIAS names in files and data structures

Relaxed rules for data structure I/O

Faster return values with RTNPARM

%PARMNUM built-in function

Optional prototypes

Implicit CCSID conversion for parameters

Teraspace storage model

CCSIDCVT keyword to notify about conversion errors

Encrypted listing debug view

V5R4

EVAL-CORR

XML-INTO and XML-SAX to process XML documents

Syntax-checker support for free-form

Improved handling of EOF for shared files

Debugger support for null values

PREFIX keyword enhanced to completely remove a prefix

More granular options for the DEBUG control keyword

7.2

CCSID support for alphanumeric data

Alphanumeric subfields in external data structures can have the same CCSID as the field in the file

Implicit CCSID conversion for concatenation

Option to open database files without CCSID conversion

/SET and /RESTORE directives to temporarily change the default CCSID or date/time format

More control for %SUBDT

0 and 12 fractional seconds for timestamps

6.1

Open Access: RPG Edition

THREAD (*CONCURRENT)

Linear main

Files defined in subprocedures

Qualified record formats

Files defined like other files

File parameters

EXTDESC keyword

Library name for EXTNAME keyword

Data structure result field for EXFMT

16 MB fields

TEMPLATE keyword

PCML stored in the module

New options for XML-INTO
