Tony, You can write a DS to a record format as follows: Write IpXB00R IpXB00O; (IpXB00R is the format as defined by the DDS.) IpXB00O is a DS declared as: D IpXB00O Ds LikeRec(IPXB00R:*OutPut) (Note: defined as *Output) I believe the manual has some errors in it as far as 'reading into' or 'writing from' these data structures are concerned. As you discovered, you cannot declare the DS with 'ExtName' as the manual says. I believe it also says you can write to a Ds to the file, but I think it has to be a format. I spent hours (may have been 10s of hours) trying to figure this out. Jon Paris had said a year ago he had reported these 'manual' errors to IBM.

But apparently WRITEing from a DS isn't allowed? I get RNF7701 - The data structure is not allowed for the operation, during the compile. I tried by declaring the file for update mode, with addtions allowed: FDFamly UF A E K Disk ExtFile('DMART/DFAMLY') And also tried by declaring it for output: FDFamlyWrt O E Disk ExtFile('DMART/DFAMLY') F Rename(RFAMLY:RFAMLYW) Why would the compiler let you read, chain and update, but not write from a DS? Is this a known, undocumented limitation? -- "Enter any 11-digit prime number to continue..." -- This is the RPG programming on the AS400 / iSeries (RPG400-L) mailing list To post a message email: RPG400-L@xxxxxxxxxxxx To subscribe, unsubscribe, or change list options, visit: http://lists.midrange.com/mailman/listinfo/rpg400-l or email: RPG400-L-request@xxxxxxxxxxxx Before posting, please take a moment to review the archives at http://archive.midrange.com/rpg400-l.
