This is a fairly reasonable question. However, it helps if you tell
us what you think it means, or what you want it to mean.

You do not show how T_INTEGER is defined, so I can't answer your
question. The general rule here is to post _compilable_ examples. That
means make a small program (called Learning_Ada, or whatever), that
defines _all_ types needed. That makes things much clearer.

Do you know that this is called a record representation clause? You
need to give us a better clue as to what you don't understand.

Post the exact error messages, then we can help.

Please try again.
