When I compile, the SYS(5) + SYS(2003) is being substitued for all occurrences of DEFAULT_APP_TREE as opposed the current evaluation of SYS(5) + SYS(2003). Right? In other words, on my development machine, this would evaluate, at runtime, to D:\Apps\DFS. On my users, it could evalute to C:\Apps\DFS.

Hi David,

I've tested this on my machine running an EXE outside the development environment. The answer appears to be that the constant is re-evaluated at run-time. My test showed the current directory, not the one the exe that was the current default when the exe was compiled. Frankly, I thought the same way you did, but apparently, this isn't the case.
