KEYS

13

Using ‘ * ‘ On the AS/400

• The * (asterisk or star) when used before a parameter value denotes a special value.Eg. *all, *libl, *curlib

• When the * is used after a parameter value, it is a wild card (just like in DOS/UNIX)

• Eg. WRKUSRPRF DB400C*

14

Commonly Used Function Keys

• F1 = Help• F2 = Extended Help• F3 = Exit• F4 = Prompt• F5 = Refresh Screen• F10 = Additional

parameters / different views

• F9 = Retrieve Previous Command

• F11 = Keyword toggle different

views• F12 = Cancel step• F23 = More options• F24 = More functions

15

Using F4 and ?

• The ? is used the same way F4 is.

• Entered into a command field, it gives you the possible values for the field.

• Entered before a command, puts you in prompt mode for that command.

Eg. ?CRTLIB

16

IBM AS/400 Help

F1 = HELP Field Level (contextual) or extended dependent on the cursor location

F2 = Extended Help

Internet

“Objects” • anything on the AS/400 that has a name, takes up space

in storage, can be acted on or executed and is not of a temporary nature” is an object

• on AS/400 files have members

• Each objects has an associated DESCRIPTION

in which both the physical and logical

attributes (properties) are defined

• Common object types include:

– libraries, files, job queues, programs

• Common sub types / attributes are CBL, CL, DSPF, PF, LF , SAVF

24

Entering source code

25

Enter Source Code using SEU

• SEU can be used for entering many types of source code e.g. DDS Data Definition Specification

C programs CL programs…

• SEU needs the source file name, the member name and the source type.

26

SEU: Source Entry Utility

• STRSEU or F6 - Create a new member within PDM

• Remember to specify TYPE attribute when starting

• Take note of the function keys available in a editing session e.g.Browse/Copy function (F15)

• can be used to browse compile listing

• can be used to copy from another member .Find/Change option (F14)

• can be used to find occurrences of words

27

Determine the “file” usage

• The source attribute type: – tells SEU what type of source you are creating

e.g. TXT, PF, LF, CL, etc– Determines which SYNTAX checker to use– Determines which COMPILER to use when

creating the object.

SEU Editor• SEU has built in editor

• SEU==>________ command line

• Line commands:– C copies a line CC…CC copies a block– M moves a line MM..MM moves a block– I inserts, In inserts n lines, IP inserts and

prompts– D deletes, Dn deletes n lines– A = after, B = before the target for move/copy

Internally v.s Externally declared files

When createdINTERNAL vs. EXTERNAL

•Single field (alphabetic) equal to record length• Fields Defined within (internal to) programs.•Record substructure (Fields) NOT globally accessible by other programs / utilities

•One or more fields defined in a DDS source file•File structure generated externally from a source member•Globally accessible by all programs and utilities

35

Compiling the Source Code

• CRTPF command or Option 14 in PDM

takes the source code and creates the object i.e. the CL executable program

How do you know if the compile worked???

• An output file is created with each compile (the compile listing) which tells you what happened. READ it!

• Where is that output file??

• In your output queue!!

40

Compile Errors

• Make sure the compile worked!

• The PDM user option SP shows you your spooled compile listing and if there are errors, a joblog.

• If errors, return to SEU, use F15 then option 2 for spool files. The system will bring up your compile listing in an additional window.

41

Compile Errors cont’d• On the lower window command line, enter

F *err (find errors)

• Pressing F1 with the cursor on the message will give you an explanation of the message

• Use F12 to return to browse window and press F16 to repeat the find errors command.

• Check out the warning messages also.
