Use of constants in FILE SECTION

Hi,

we use level 78 constants to keep our data consistent e.g. LENGTH-PATH, LENGTH-CITY etc.

So in the WORKING STORAGE SECTION we only need

03 CUST-CITY PIC X(LENGTH-CITY).

The problem is that we want to use these also in the FILE SECTION.

But our source only compiles correctly if the first statement of the FILE SECTION is an FD.

Do you have an idea how to solve this issue ?
