Thank you and this is good to know. a coupe of questions, please. 1. this suggest the limit to the number of files to be appeneded is realted to machine memory? 2. this is the solution to the "lack" of ability to dynamically read multiple files?
Would those of you who have used these techniques please let me know what size of the files you have been working with and, any other options you have used.
Thank you very much, Kelly

Dear Eleni: There are two ways to append - one is within EpiData, the other highly efficient within EpiData Analysis. If you append (not merge) files with the same same structure, try this in EpiData Analysis, ver 0.9 build 38: * ----Program begins next line cls logclose close * switch to the folder where your REC files are located cd c:\temp1 erase "abcd.rec" read "a.rec" append "b.rec" append "c.rec" append "d.rec" savedata "abcd.rec" close * Do some tabulation to check read "abcd.rec" tables sex res1 logclose * --- Program has ended previous line Best regards, Hans -- Hans L Rieder, MD, MPH Jetzikofenstr. 12 3038 Kirchlindach Switzerland Tel: +41 31 829 4577 Mob: +41 79 429 9945 Web: http://www.tbrieder.org
