It's not going to make any difference.
The scanner also has to read and convert decimal numbers from text strings.
Did you think computers use decimal internally?
Please use whichever base is more readable.

These appends and prepends will be performed at run-time,
not parse time, and unless you have many thousands of them,
you won't notice any difference.

I would say write your code in as readable a manner as you can,
and forget about trying to shave a millisecond off your load time.

The parser is open source. Any one can study it and recommend
ways to speed it up.

Something that actually *will* improve your load time,
on very old, slow machines with small RAM, 
is to remove any "with trace", "with profile" or 
"with profile_time" statements that you are 
no longer using. This will also help you at run-time.
You should search your copy of Win32Lib, IDE etc. to see 
if any were left in there.

And of course you can achieve *zero* parse time
if you bind, shroud or translate any large program
that you use a lot. For smaller programs, 
under about 10,000 lines, I wouldn't worry about it.
