Re: [U2] select query..
You should not need to do the SAVE-LIST and GET-LIST unless you wish to do a 2nd pass on the exact same results. The main purpose of a SAVEDLIST is to prevent you from having to do the same select multiple times (or to preserve the list of keys for some other purpose). Note that a SAVEDLIST is just a list of KEYs and no other data. I do not understand what is in KEYVALUE. I am assuming you are running in native UniData/UniVerse mode. If you are always wanting the same records, just build a permanent SAVEDLIST, get it and never bother with a SELECT again.

Re: [U2] select query..
I'm confused.. If your doing a select with @ID = you will only get 1 response each time, @ID is a primary key field.

An alternative to a SAVE.LIST and GET.LIST could be to open SAVEDLISTS as file Then READ and WRITE your dynamic list to that file, and just use a FOR/NEXT loop to Traverse it.

Re: [U2] select query..
That's what READLIST and WRITELIST are for. I've found writing the list as MY.LIST000 to be relatively safe, when you read you would have to check for MY.LIST000, then MY.LIST001, etc. Sathya - as Mecki said, if you're using the @ID of the file you can do a straight read to check if it's there.
