 Andrew,
You don't need a subroutine record for this. You might be able to get it into a
single calcout

record using techniques folks have already mentioned, but as they've noted, the
result might

be hard to understand.
I would do this with a transform record, if the record is available.

You'd have 16 calc-type expressions, each with a comment to describe it, all in
one record,

so you could break this into separate expressions and then combine the results.
For example:
    field(CLCF, "235>B && 5>D && 5>E")
    field(CLCG, "B*0.00835-0.7")
    field(CLCH, "A+(C-B)*0.25")
    field(CLCI, "F?(G>H?G:H):0)
Actually, I'd rewrite that last expression as
    field(CLCI, "F?MAX(H,G):0")
This seems to me easier to understand and modify than the equivalent implementation
with calcout records.
