Thanks again...but...
May I ask some specifics.

Question 1) Will AS "wait" for the action to be completed eg
moving a file
2) How does it know that the action has been successfully
transacted ( assuming the answer to 1 is yes)
3) Is it ever possible for a loop to "outpace" it's asked for
action.
1) In general, when a script tells an application to do something,
it sends a message to the application, and waits for the application
to send back an "I'm done, and here's the result" message before it
continues.
So, is it as easy as checking for "Empty" to know if an action was not
carried out? Let's say the command is to "Delete a file". Would the
result be "File Deleted". Or let's say the command was to "Find a
file"...Would you expect a "not found" to produce and error or simply
return "Empty". I guess I am trying to get a feel for the syntax of AS.
3) The script can also use the "ignoring application responses"
modifier to just send the message to the application, and not bother
waiting for a reply. In this case, the script has no direct way of
knowing when or if the operating has completed, but it can use
indirect methods to check (for example, looking for the file in the
destination folder).
I tried this and it seemed to work well....when it worked!
4) In theory, if you don't use "ignoring application responses" a
script shouldn't be able to "get ahead of" the application, since it
always waits for the application to complete an operation before it
does the next thing (see 1).
I guess in my case, it **may??** be different..but maybe not. I was
using RB to compose and write the App that searches, asks for user
input etc. Then, when a list of files ( emails) are defined, I simply
ran a loop sending AS commands ( each specifically composed for a
particular file/email) to move that e-mail. The result was really hit
and miss. Sometimes the emails were moved, sometimes only part of the
list was moved, and if the list was really big ( artificially made so
my me to test the program) it often just failed after say 10 or 20 of
a 12,000 list of emails. I was also not that tuned into the finer
details of AS that I could adequately troubleshoot it...but I think
your explanation has helped. ( You said at one point you slowed down
a loop by inserting a one second delay.)
