Just a wild guess, Mike - the first parameter of DLVALUE is supposed 
to be a URL, I believe - the docs at V5R2 says it needs to have a 
scheme and server - try adding file://localhost in front maybe. I've 
not done this, had no need to work with data links yet.

There should be more information at second level - please post it. 
Easiest way to get it might be DSPJOBLOG OUTPUT(*PRINT) and copy-paste 
the relevant section.

I'm trying to make use of Datalinks.  I am working through an article

in the IseriesNetwork from Jan of 01. " RPG IV "Crib Sheet" for SQL 
DataLinks" I've gone through all the steps, however, when I run the 
sql

statement to populate the datalinks I get the following error.
 Data mapping error on member QSQPTABL.
 Data mapping error on member QSQPTABL.
 Data mapping error on member QSQPTABL.
 Error 21 occurred using DataLink data type.
 RUNSQLSTM command failed.
 RUNSQLSTM command failed.
Error type 21 is format of DataLink value not valid.

I have searched the archives and found some references to this, but I

haven't come across a solution.

Anybody have an idea what is causing this and how to correct it?

Thanks.
