The LE Programming Guide discusses downward compatibility (as of OS/390 2.10).
Don Imbriale -----Original Message----- From: IBM Mainframe Discussion List [mailto:[EMAIL PROTECTED] On Behalf Of Lizette Koehler Sent: Wednesday, November 08, 2006 12:29 PM To: [email protected] Subject: z/OS V1.4 and v1.7 with Language Environment We are planning to upgrade from z/OS V1.4 to V1.7. There has come up a concern over having z/OS V1.7 Language Environment in the TEST/DEVL systems and not in production. That programs compiled and LKED with the newer LE would have issues running in the V1.4 LPARS. I was thinking of just taking SCEELKED and leaving the V1.4 version in TEST/DEVL until V1.7 is on the production LPARS. Does anyone have any indication whether or not we need to leave the V1.4 version in TEST/DEVL or if the V1.7 can be in TEST/DEVL and rolling out to V1.4 LPARs. Does anyone know of any other application specific concerns with LE? *********************************************************************** Bear Stearns is not responsible for any recommendation, solicitation, offer or agreement or any information about any transaction, customer account or account activity contained in this communication. *********************************************************************** ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
