Thanks Mike,

>>1) There are values related to the calendar e.g. Days of week or names of months in spanish. You may consider these to be "permanent" values.

What I need is more of an array so that I can say:
? gaDiaSemana[DOW(DATE()]
I think I'll go with oApp.aDiaSemana[]


>>2) Values established by law for all clients. I keep many of these in a table, but I find it better to load them up to memory and work from there since table isn't always in right record. Perhaps an object which represents that table?

OK

>>4) Values that have to do with the company (user may have several). oCompany?>I normally leave these as table records. Or, instead of saving the fields as properties, create an object with a method that will return a value from the correct record and field.

Some are best kept as in table, such as address, etc, but I have a parameter file where many user options are stored. Some are used infrequently, so I get them as I need them, but others are used more regularly, and I think it's best not to look into the parameter file frequently. I think it's best if they don't go in oApp, since they are not totally global.


FWIW, I'll describe the parameter setup I use which although similar to MaxFrame's, I think is better :).

PARAMETER TABLES:
1) An internal (in the project) file. (xxParInt).

2) An external file (xxPar). It resides with company data. Since user may have more than one company I am considering having a site parameter file which would reside in application directory, which has intermediate priority.

3) Can override an internal parameter with the external one.

4) File structure, same for all files.
cGroup C(40)
cParameter C(40)
cType C(1) - C/L/N/P/A (Char,Logic,Numeric,Program,Array)
cValue - If cType='P', contains object code.
cDescription - If cType='P', contains source code.

INTERFACE ROUTINES.
GetParam(tcGroup,tcParameter,tuDefault[,tnArrayRow])
GetParamList(tcCondition,taArray,tnMaxRowLength)
PutParam(tcGroup,tcParameter,tcType,tuValue)
