AS/400 Command Syntax: Tips, Questions, and Library Management

This review covers key aspects of AS/400 command syntax, including the use of parameters, the significance of pressing F4 instead of Enter, and how to manage library lists. It addresses whether all commands have parameters, discusses positional and keyword syntax, and explores various menu groups related to commands. Additionally, it explains the structure of the AS/400 data storage hierarchy, manipulation of spooled files, and job management commands. Key concepts are reinforced with practical examples, ensuring a practical understanding.

  1. Last Week’s Review Any Questions?

  2. CL Syntax Command-name (space) parameter

  3. CL Syntax • Do all commands have parameters? • Why should you always press F4 following a command instead of enter?

  4. Positional or Keyword? By Keyword, both these are allowed CRTLIB LIB(PAYROLL) TYPE(*TEST) TEXT(‘Payroll Development’) CRTLIB TYPE(*TEST) TEXT(‘Payroll Development’) LIB(PAYROLL)

  5. Positional • Allowed: • CRTLIB PAYROLL *TEST • Not Allowed • CRTLIB *TEST PAYROLL

  6. Syntax Question • How could you find the keyword syntax to Create a Physical File named EMPPF in Library IBC233LIB with a record length of 120 characters?

  7. Menu Questions • Which menu groups together all of the Work With commands? • Which menu groups together all of the commands by subject?

  8. Menu • Menus GO MAIN main menu (F16) GO MAJOR major commands menu (F4) GO VERB action menu GO SUBJECT objects menu GO CMDxxxx verb, noun, function

  9. 4 Parts of a Library List (or the 4 library list types) • System (SYS) • Product (PRD) • Current (CUR) • User (USR)

  10. Library List Commands • ADDLIBLE • Adds an entry to a library list to the USER portion of the library list • RMVLIBLE • Removes an entry from the USER portion of the library list • EDTLIBL • Adds/Deletes/Changes entries on the USER portion of the library list

  11. Library List Commands • CHGCURLIB • Changes the Current Library • CHGLIBL • Changes the Current Library and allows Add/Change/Delete to the USER portion of the library list. • All Library List commands are listed on the CMDLIBL menu.

  12. Data Storage Hierarchy MOHAMED - *LIB IBC233LIB - *LIB DA233x99 - *LIB Reviews *FILE DA233x99 *OUTQ Object1 *PGM Review1 Reviews *FILE Review2 Object2 *OUTQ Review3 Review1 Labanswers *FILE Object3 *FILE Review2 Answers Lab1

  13. Objects Chapter 3

  14. Today’s Lecture • Use of ‘*’ on the AS/400 • Use of ‘?’ on the AS/400 • AS/400 Architecture • Object Types • Storing Objects • Manipulating Library Lists • Spooled Files • Work with Jobs Commands

  15. What does the ‘*’ denote?

  16. ‘*’ (Asterix) • When used before an ‘AS/400’ word, indicates that the word is a special value.eg. CRTLIB LIB(MYLIB) TYPE(*TEST) TEXT(‘Test Library) • When used at the end of a word, indicates a generic combination of alphanumerics (wildcards).eg. WRKLIB TST*

  17. Use of the ‘?’ • Entering a command to see all possible values for a parameter. • F4 does the same

  18. What is an Object?

  19. Objects • Takes up Space on the AS400 • Has a Description • Has an Object Type

  20. Object Types

  21. A Library Search

  22. Object Types • Certain types of commands only work with certain types of Object Typeseg. DSPUSRPRF • Object Type is assigned to the Object at time of creationeg. CRTLIB creates objects with a type of *LIB

  23. How does the AS/400 find Objects?

  24. AS/400 finds Objects • Qualified Names Library/Object IBC233LIB/REVIEWS • Using Library Lists! How are Library Lists sequenced?

  25. AS/400 finds Objects Note: Library Descriptions, Device Descriptions and User Profiles are stored in QSYS. All other Object Types can be stored anywhere.

  26. What is a Spooled File?

  27. Spooled Files • AS/400 objects that contain data for printing • Are stored in Output Queues • To print a Spooled File, the file must be moved to an Output Queue attached to a printer.

  28. How Do Spooled Files get Created? QINTER Output Queue Job Program/ Command Spooled File Report Layout Data *FILE *FILE

  29. DC234X99 PRT01 SPLF#1 SPLF#3 SPLF#2 SPLF#4 Change the Spooled File to OutQ PRT01

  30. Work with Jobs Command • To display information about your current Interactive job, simply type: WRKJOB • To display information about any other job, use the Work With Job and enter the Job Name and User. Number is Optional. • To display your Batch Jobs, use the Work with Submitted Jobs Commands (WRKSBMJOB)

  31. WRKUSRJOB • Shows you a list of all of the jobs that you own on the system irregardless of the subsystem • Status • Active = Job is currently running • Outq = Job is finished • Jobq = Job is waiting to process. • To delete a ‘run-away’ job, take option 4

  32. Problems ? • Enter GO SENECA on the command line. You will get a menu for information on fixing your user profile if you cannot sign on.

  33. Test 1 Date IBC233 - Friday Sept. 26, 2003

  34. Before Next Lab • Reread Chapter 3. Maybe now it makes sense • Print Lab 3.

  35. Before Next Class • Do the Review Questions for Chapter 3. • Read Chapter 11.
