OK, I would just make a list of the objects, since one of the attributes is the
name you have everything you need in the object.
def getNames():
import os
currentDir=os.getcwd()
temp=currentDir + '/TEMP'
os.chdir(temp)
baseList=os.listdir(".")
data = []
for name in baseList:
data.append(TPROJ(name))
print name
return data
then to use the data something like
for datum in data:
f = open(datum.name, 'w')
#etc
