Thanks all who replied so quickly (two Franks, Chipp, Rob and Alex!
I may have misled some readers by my example where the files were called A01, A02 etc - this was just an example. In fact they're just the titles of text files that need a certain kind of conversion: the titles reflect the contents and aren't really a numerically complete set. Also, I didn't want to open the file for the user, since in some cases he/she might choose to skip it. What I wanted to do was to point directly at the file to prevent all that tedious scrolling which one gets in OS 'open' dialogs that don't remember the last file you opened but just start at the top of the list again. As far as I remember, Mac OSX is worse at this than OS9 was.
This is why Alex's idea would work best for me if I could make it work:
This is actually much easier than you might think ....
The docs for "answer file" sayThe defaultPath is the name and location of the folder whose contents are
listed when the dialog box appears. If no defaultPath is specified, the
dialog box lists the contents of the last folder you used with a file
dialog box.
But in fact, the defaultPath can be the name and location of A FILE within
a folder.
Thus, for example,
answer file "Test" with "D:/Our Documents/Alex/RunRev/Boggal.rev"
opens the dialog at the correct folder, with the file "Boggal" pre-selected.
So you can allow the user to open the first file as normal, then on subsequent opens, do something like
set itemDel to "/" put item 1 to -2 of lastFile into theFolder put item -1 of lastFile into theName put theFolder & "/" into theDefault if lastFile <> "" then set the defaultfolder to theFolder put the short files into fList sort flist set wholeMatches to true put lineOffset(theName, fList) into t if t > 0 then put item -1 of line (t+1) of fList after theDefault end if end if answer file "Your Prompt" with theDefault put it into lastFile
(I'm sure you could re-write that code fragment into something neater - but
it does work :-)
The trouble is, my version of this code displays the right folder and within it the usual scrolling file list (this is OSX) but it doesn't preselect the file. Strange, since it worked for Alex, but I have quite carefully tested that my equivalent of his 'theDefault' is the complete path to the last file read (I've not yet reached the refinement of picking the actual next file).
I guess I may have to go back to one of the private-list based solutions.
