Maybe you will use PoolDictionaries. See pool/class "FFIConstants" in FFI package for example. Check the class side #initialize method where the values are assigned. SharedPool subclass: #FFIConstants ... It is used in ExternalFunction for example: ExternalObject subclass: #ExternalFunction instanceVariableNames: 'flags argTypes' classVariableNames: 'FFIErrorMessages' poolDictionaries: 'FFIConstants' category: 'FFI-Kernel' Bye Torsten BTW: Would be nice if Pharo will support scoping for pools later, something in the like of Win32OLEConstants::S_OK Win32Constants::S_OK -- Jetzt kostenlos herunterladen: Internet Explorer 8 und Mozilla Firefox 3.5 - sicherer, schneller und einfacher! http://portal.gmx.net/de/go/chbrowser
