I need help helping someone. They are using Excel on a Mac and apparently I
know even less than I thought I did about programming in VBA on that platform.

Can anyone point me to some code snippets or help regarding these areas:

#1: Using Application.GetOpenFilename() on that platform? User gets Error
1004 when trying it the Windows way.

#2: Once I've got a file path/name, how to open it for read? The file is
actually a text file, one field of a record per row, with several rows making
up one record. To be specific, trying to read a QIF file - Intuit Quickbooks
format.

#3: proper code to do the equivalent of
Do While Not EOF(#filebuffer)
Line Input #filebuffer, OneLineFromFile
.....process that text data
Loop

and of course, How to properly close the text file.

This whole exercise is making me feel quite inadequate!
