Usability:
you will read back a current and a voltage from the power supply.
Is HOPR/LOPR the display range for the current or the voltage?
Of course you can have an IHOP/ILOP and VHOP/VLOP, but since there is
just one function get_graphic_double, no standard display will be able
to use those fields context sensitive.
The same applies to ADEL, MDEL, HIGH, HIHI, LOW, LOLO, ....
Actually, get_graphic_double gets a DBADDR* argument which references the field,
not the record. Thus, it is possible to provide different values for different
fields. But one has to do this. Many existing records already failed to
implement this correctly (e.g. calc uses the same HOPR, LOPR, PREC, EGU for
fields A,B,C,... as for VAL, motor uses the same PREC for ERES as for VAL, ...)
I agree with Andreas: Better not add another "generic" mega-record which at the
end is more restrictive than generic. At least not until real object oriented
inheritance is implemented for records.
