I wanted to add a workspace list into my main.h header file

example:

_MAINTABLE1 3
_MAINTABLE2 7

then in the program I want to include the header file and select the workspace number by using the header file, example:

Select _MAINTABLE1 &&& to use workspace 3 for the table

I always get errors when I try to use the header variables in the select command trying it different ways.

Is it possible to use these in a select command? If so, what is the proper syntax for it?
