Razzak, Further to your earlier reply, what I am wanting to do is to define a function which combines two integer values and a text value to form a real value which will then uniquely define an item matching a row in a table. (I have a computed column which does this in the table, and I assume that this will make the lookup faster, when the computed column has an index, rather then using a combination of where clauses. The reason for using the three columns is because that is the way the items are referred to in the 'real world' and I can't change that. )
Can you please advise the most efficient way to do this - is a UDF what I should be using or can I do this using a Plugin ? Your advice would be much appreciated. Thank you.

John, Anyone who knows a little bit about Delphi, should be able to write a UDF or even better, a PLUGIN for R:BASE 7.x and V-8 Turbo for Windows. To get started with a sample code and all steps necessary, refer to the sample codes included with the R:BASE 7.x and V-8 Turbo in-line HELP. A the R> prompt, type: HELP PLUGIN or HELP | INDEX ... Type in the keyword to find: "PLUGIN" Type in the keyword to find: "SAMPLE UDF" Should you need further assistance or more samples, feel free to contact RBTI Development Team at: mailto:[EMAIL PROTECTED] Very Best R:egards, Razzak. -- No virus found in this incoming message.
