'fixed the previous fix - replaced all instances of 'expr' with 'xref'
'also now checking for initial single quote in xref, and if found
'advancing past it to get the full pathname [dumb, really dumb!]
'-----------------------------------------------------------------
'2004-03-25
'revised to check if filename in xref exists - if it does, proceed;
'otherwise, return a #REF! error immediately - this avoids Excel
'displaying dialogs when the referenced file doesn't exist

'Credits:
'- Designed and written by Wilson So.
'- The 'CreateObject("Excel.Application")' trick was inspired by Harlan Grove's PULL function source code.

'This is an open source. You can freely redistribute and modify it, but please kindly give credit to the contributers.
'Please also kindly report any bugs/suggestions through e-mail or in the forums where I posted it.
'------------------------------------
'How to use:
'- Basically same as INDIRECT() in Excel - the same concept for the ref_text parameter.
'- To update the static memory for a particular reference,
' type TRUE in the second parameter (just one of the IndirectEx() containing that reference)
' and calculate it once.
'------------------------------------
'Features:
'- You can refer to the closed workbook data.
'- The retrieved closed workbook data will be stored in the static memory,
' so in the next time, the closed workbook will not be opened again for fast retrieve.
'- A range instead of an array will be returned if the path is omitted in the ref_text,
' so it still works fine if the user refers to an enormous array, e.g. "Sheet1!1:65536".
'- You can use it inside INDEX(), VLOOKUP(), MATCH() etc.
'- You can use it with OFFSET(), but only for opened workbook data.
'- The procedure will not blindly retrieve all the data as requested;
' it will not retrieve data beyond the "Ctrl + End" cell, in order to keep the memory as small as possible.
'- #NUM! will be returned in case of lack of memory.
'- #REF! will be returned in case of a wrong path.
'- #VALUE! will be returned in case of other errors.
'------------------------------------
'Known issues:
'- Due to the use of SpecialCells(), #VALUE! will be returned if the worksheet for a closed workbook is protected.
