Re: CALC expression

[Tim Mooney <mooney@aps.anl.gov>]

 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.
