> Why not just have the table entries linked with a "next" pointer ? Binary searching of the tables after they have been loaded. > Have a second buffer for the table. Good thought. There are three tables involved, which are already very large (75 meg between them). I'll look into a fourth for buffer space. -----Original Message----- From: IBM Mainframe Assembler List [mailto:ASSEMBLER-LIST@LISTSERV.UGA.EDU]On Behalf Of Beate Kawelke Sent: Friday, September 30, 2005 9:14 AM To: ASSEMBLER-LIST@LISTSERV.UGA.EDU Subject: Re: Shifting memory to the right Hmmmm - two thoughts: 1. Why not just have the table entries linked with a "next" pointer ? If necessary, throw in a "previous" pointer, too. Navigation through the table is quite easy, and you can add / delete entries simply by chaining them in the right place. 2. Have a second buffer for the table. Move upper part to buffer, then the new entry, then the lower part.
