EXPAND=NO will keep the cell pool limited to 1MB (approx. size as it is possible that any related housekeeping control blocks will eat into the total "data" available)
EXPAND=YES will allow IARCP64 to chain multiple 1MB memory objects together to increase the logical cell pool size beyond 1Mb Rob Scott Lead Developer Rocket Software 77 Fourth Avenue . Suite 100 .

"Make it any size you like, but for gosh sakes don't make it any bigger than that"? The documentation reads like transistor radio instructions from the fifties: ,EXPAND=NO This parameter does not try expanding. The documentation is REALLY deficient IMHO: 1. Apparently nada in the Services Guide. No overview. No usage. The example in the reference is just a rehash of the parameters. 2. Documentation appears to be 100% duplicated between Services and Authorized Services. If there is a reason for it being in both places the reason escapes me. I don't see any "special" parameters documented only in Authorized Services. 3. If the size works as Dave suggests -- and I have no reason to doubt him -- that rather counterintuitive point would be worth mentioning in the doc.

I asked the same question some time back, and was told that this is 64 bit stg. No need for these types of parameters. My gut tells me it gets stg to back the cell pool in 1 meg increments, but have not done anything to verify that. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN ================================ Rocket Software, Inc. and subsidiaries ■ 77 Fourth Avenue, Waltham MA 02451 ■ +1 800.966.3270 ■ +1 781.577.4321 Unsubscribe From Commercial Email – [email protected] Manage Your Subscription Preferences - http://info.rocketsoftware.com/GlobalSubscriptionManagementEmailFooter_SubscriptionCenter.html Privacy Policy - http://www.rocketsoftware.com/company/legal/privacy-policy ================================ ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
