I just want to point out two things here. First, using an expression like this, every place you use the constant, the expression has to be evaluated. This is a case where it's probably better to evaluate once into a variable or property of an app object and then use the computed value repeatedly.

Second, if you do want to stick with the expression, FORCEPATH() makes the first two more obvious than a simple concatenation does:

ADDBS(FORCEPATH("Graphics", CURDIR()))
