A former co-worker left us with thousands of lines of code looking like this. This is more a curiosity, since I rewrote everything he did in less obscure languages :-)

Nevertheless I'm curious. Is this meta-code or an actual language?

```
  DATA DIVISION.

   WORKING-STORAGE SECTION.

   01 Display-Error.
      03 Display-Error-No             PIC 9(4) comp-5.
      03 Display-Details-1            PIC 9(4) comp-5.
      03 Display-Details-2            PIC 9(4) comp-5.
          05 Display-Details-3            PIC 9(4) comp-5.

   COPY "ThisApp.txt".
