I recently started programming using Think C.  I would like advice on a 
simple, beginner's question for which I cannot find the answer in 
Inside Macintosh.

I have stored tables of 64 doubles as different IDs of resource type 'CDNT'.
My program will load one table from a specific ID (chosen by the user) and 
use the doubles in the table in a long series of calculations.  For 
simplicity, I want to lock the handle to the resource so I can use a
pointer in my calculations.

I realize the size of this resource (640 bytes) is small, but I would like
to know which is the best strategy for locking the handle:

1)  I could set the "locked" attribute in the resource file, so that the
    handle is locked immediately when the resource is loaded into the
    application heap.

2)  I could get the resource without the "locked" attribute set, then
    MoveHHi( myHandle ) and HLock( myHandle ).
    
Thanks in advance for any help.  E-mail replies will be sufficient, altho
I read this newsgroup regularly.
