Exactly. Make a "times" record/object/tuple (whatever the local custom you have for an aggregate type is), perhaps with a "tenth" nested such item (10% = 1/10)

Exactly. Make a "times" record/object/tuple (whatever the local custom you have for an aggregate type is), perhaps with a "tenth" nested such item (10% = 1/10), with "fall" and "rise" members. times.tenth.fall times.tenth.rise Hopefully, they aren't using some ancient version of FORTRAN. My first paid work in the 80s was in a language with 8 or 10 character long names, depending on use, with only scalar values outside of ISAM tables. One compiler variant extended that with arrays (but not nested arrays). You had no choice but to make some weird names. That said, when I started doing ANSI C with 32 char names, I felt like I had failed when I needed a variable that had to be that long to explain what it did. Either it had too broad a scope, or should have been bundled in something else (record/struct).
