Sounds like you still need a Python softIoc expert then.
It might be helpful if you post the output of
dbpr("XX:CALC", 2)
and
dbpr("XX: VALUE", 2)
though so we can see what it sets all the fields to though.

Andrew,
That loads without error. But the calculation doesn't actually work.
#!/usr/local/epics/modules/pythonIoc/pythonIoc
from softioc import softioc, builder
builder.SetDeviceName('XX')
rec = builder.aIn('VALUE',VAL=3)
calc = builder.records.calc('CALC', CALC = 'A*B', INPA = rec, B = 42)
rec.FLNK = builder.PP(calc)
#run the ioc
builder.LoadDatabase()
softioc.iocInit()
#start the ioc shell
softioc.interactive_ioc(globals())
===========
$ caput "XX:VALUE" 7

According to the documentation, this should work:

from softioc import softioc, builder
builder.SetDeviceName('XX')
rec = builder.aIn('VALUE')
calc = builder.records.calc('CALC', CALC = 'A*B', A = rec, B = 42)
rec.FLNK = builder.PP(calc)
I’ve never used the Python softIoc, but given this error message
AssertionError: Can't write "XX:VALUE" to field A: not a number
have you tried this instead?
calc = builder.records.calc('CALC', CALC = 'A*B', INPA = rec, B = 42)
