Imagine you have typed in a dataset name in your ISPF EDIT session. Now you want to see the contents of this dataset. Place the cursor somewhere in the dataset name and press a function key of your own choice. A new ISPF EDIT session shows you the contents.

You have probably access to a similar functionality already. Now imagine another or the same ISPF EDIT session. You have typed in a SQL statement. Place the cursor on the first SQL keyword in the statement and press the same function key. The SQL statement is executed, just like that. If it is a SELECT the result is displayed in a new ISPF VIEW session.

Now image you are writing a SQL statement, but you have forgotten some of the column names. Place the cursor on the table name and press the same function key (again!). The columns are displayed as MSG-lines below the table name.

This is what CXU is all about. Place the cursor at a name or datasetname in your ISPF EDIT/VIEW session, press the CXU function key and see what happens! Just that simple. Click on Download, then you are well underway.

Oh, I completely forgot to tell you that CXU is also easy to install and configure. You can do it yourself. CXU only requires that you are running a TSO session with ISPF and that you can transfer data from your PC to the TSO session.
