Dictation within a context-free grammar |

Greetings,
I am trying to assemble a fairly simple grammar (see XML below) for speech
recognition, and the format of my grammar is as follows:
"order sell [quantity] at [price]" (or)
"order pay [price] on [quantity]"
Where quantity is some integer value and price is some floating-point value.
In each possibility there are two "dictation" elements where I rely on the
SAPI dictation engine to decipher the numbers in this case.
I would *like* the engine to normalize these dictation elements, so that if
I say "three hundred and nineteen" or "three point four" it will
automatically normalize the text into 319 and 3.4, respectively. The SAPI
engine *will* do this if I simply load a grammar and call DictationLoad or
DictationSetState = Active, however if I have Dictation rules embedded within
a context-free grammar I'm defining, it will not do this text
replacement/normalization.
So if I say:
"order sell three hundred and nineteen at forty five point five"
that's exactly what I get -- the numbers are all spelled out. What I want is:
"order sell 319 at 45.5"
How can I get the reco engine to perform this normalization *within* my
grammar at these dictation points?
Thanks,
Rick
My grammar:
order
sell
at
pay
on
