define default block with base table LINES add field to this block as non-data base field Then define post-query select tname into :block_name.non-data base field name from treatements
where tcode = :block_name.tcode

the post-query trigger will fire after each row is returned.

I usually use the screen painter to select, cut, and paste, so that the fields are on one line (one may change the definitions under fields of the X and Y cooridinates also) and then modify the block to show multiple lines on that page

with the default block definitions all keys defined in your oraterm.r or whichever keymapping are available... use your trigger definitions to manipulate the key-commands to do more than what is standard.

I started with the default blocks and built up triggers etc... as I learned sqlforms.
