I have the following button on my form:

method pushButton(var eventInfo Event)

var
qvar query
tv TableView
endvar

const
Prefx = String (":Nchi")
endconst

qvar.readFromFile(Prefx + ":ArchDom" + ".qbe") ;Read in QBE.
qvar.executeQBE(":PRIV:ANSWER.DB") ;Execute QBE.
tv.open(":PRIV:ANSWER.DB")

endMethod

Why is it that this runs normally if the working directory is :NCHI, where the table is, and :PRIV:ANSWER cannot be found if I run the form from another working directory?
