ABORT CANCEL can make the SAS Workspace go away (ending the SAS session) -- although it's supposed to cancel only the currently running code. These operations have been refined in later versions of SAS and EG, so I can see where EG 4.3 might have a problem. EG 7.1 works with SAS all the way back to SAS 9.2, so there is little risk in upgrading. But I do appreciate the struggle of working in a tightly controlled IT environment; change is slow.
