Hi, I forwarded this note to Rochester. Please see the following from my COMMON presentations: V5R1 Library List Enhancement: The correct spelling of the word "enhancement" is "fiasco". In response to numerous customer and ISV requests, IBM is increasing the length of the user portion of the library list from 25 to 250 libraries effective in V5R1. Although IBM developers understand that this change will impact some users, they contend that this is in the best interest of the long-term interest of the platform. The speaker disagrees, and feels that this could break your applications. This would be the significant first change in the history of the System/38, AS/400, iSeries platform that will break users code, forcing you to make changes to keep existing applications working in the event that those application encountered more than 25 libraries on the user's portion of the library list. The following is an example of some pseudo code that would have to ultimately be changed: DCL VAR(&USRLIBL) TYPE(*CHAR) LEN(275) DCL VAR(&CMD) TYPE(*CHAR) LEN(6000) RTVJOBA USRLIBL(&USRLIBL) CHGLIBL LIBL(MYLIB1 MYLIB2 QGPL QTEMP) /* Do my thing, sing my song, yada, yada, yada */ CHGVAR &CMD ('CHGLIBL LIBL(' *CAT &USRLIBL *TCAT ')') CALL PGM(QCMDEXC) PARM(&CMD 6000) If you did not have access to your source code, or did not have support from your ISV, the above code would break. Retrieving a user library list into a variable of insufficient length would cause a new escape message of CPF098A. To minimize the impact of this change, IBM has created a new data area in V5R1 (QLILMTLIBL in QUSRSYS) that acts as a system wide switch only allowing access to the first 25 libraries in the all commands that support a library list parameter. The data area will not be shipped in V5R2, and in fact will be deleted when you install V5R2. You have the option of saving and restoring it after the install of V5R2, or recreating it. The functionality of the data area will be honored in V5R2, but not in any follow-on release. Detailed documentation about this change can be found at: http://www.iseries.ibm.com/developer/os400/lib_list.html If you feel that this is an inappropriate change, you might want to express your feelings to an employee of the IBM Corporation.

Al should get a kick out of this .... We are planning our upgrade to V5R1. In our discussion with Lawson (our GL, procurement software vendor), they indicated that their software would 'break" if we enabled the new 250 library list feature of V5....
