Have you read up on the READ command in the CICS Language Reference (link at the top of this page)? Did you see how many keys can be specified in the command (i.e., one)? So how do you provide a primary key value AND an alternate key value in one field?

Hello,

You have not been very specific about what you want to do (no field names/example data).

From the little you have posted, you might consider adding another alternate index that contains both the primary key and this particular alternate.

There might be storage or performance considerations so this shouldn't just be thrown in to solve one program requirement.
