Well, likewise Dan - I appreciate you doing it. I'm sure everyone can
relate to making an honest mistake and we've all had memory lapses.
What I will remember of this is that you dealt with it very decently.
Not everyone would have done that. :-)
Richard, any idea about the memory-leak issue I've read about when
trying to resolve invalid aliases?
Hmm. I seem to recall that Emmanuel noted it & that it was to do with
dead or orphaned aliases, but that's about all I can remember and I
don't think I kept that thread - sorry. :-\
Someone else will recall it more clearly I'm sure: Emmanuel? Nigel?
on testPathExists(inputPath)
-- version 1.4
-- Dan Shockley, email@hidden
-- CORRECTION, Richard Morton's
-- gets somewhat slower as nested-depth level goes over 10
nested folders
if inputPath is not equal to "" then try
get alias inputPath as string
return true
end try
return false
end testPathExists
Or, how about this even:
on testPathExists(inputPath)
-- version 1.4.1
-- Dan Shockley, Richard Morton
-- gets somewhat slower as nested-depth level goes over 10
nested folders
if inputPath is not equal to "" then try
get alias (inputPath as string) -- coerce to string,
then test for existence
return true
end try
return false
end testPathExists

Holy mackerel Batman! How did we end up here? I thought this thread
was on macscrpt... ;-)
