Personally I don't understand prefixing variable types. 

Other than file fields, which are all caps, and basing pointers which we end
in "Base" we have no variable type "tagging". 

IMHO the context that the variable is used, and/or its name, should tell you
what the variable is, if you are still not sure and need to know exactly,
look at the compile listing.

As far as variable name length, whatever length feels comfortable and
identifies the data held by the variable.

long name.  I try to organize the long name to make it meaningful
within the application as a whole.

all constants start with "con"

use a "_" character to group sets of constants.  kind of the
equivalent of the enum in c++:
    conItStat_Open
    conItStat_Closed
    conItStat_Ready

where "con" means constant
"itstat" is a field name in the database
what follows the "_" are the meaningful names of each permitted value
for that field.
