How do I enable the CALL and REGISTER functions in Excel 2003?

[Guest]

I want to use the CALL and REGISTER functions to call external .DLL functions
from Excel 2003. However my Excel 2003 does not recognize those functions. Do
I need an add-in or something for those?

The call function was disabled quite a while ago for security reasons. I
suspect the register as well.

I've had no need to use these function, but if you make Declare in a module,
you can then call the function from the worksheet.
