given your example,
gdict['theFile'] = theFile
does in fact do what you want.
if you want "tpairs.py" to know it's own name, you could add it to
theDict *before* you call execfile:
# doit.py
theDict = {"__file__": theFile}
execfile(theFile, theDict)
# in tpairs.py
gdict["theFile"] = __file__
but why you want a script to access its own globals via a dictionary is
more than I can figure out...
