Generic name for User Procedure folder ?

Hi
I have a bit of a code that includes loading a spreadsheet with parameters. I would like to be able to share it.
Is there a way to specify the path to the "User Procedures Folder" in a command line?
such as in a XLLoadWave ?
Take a look at the SpecialDirPath function.

Thank you !
For reference, I used :
string UserFileNm=SpecialDirPath("Igor Pro User Files",0,0,0)
UserFileNm+="FileNm.xlsx"
XLLoadWave/o/S="Sheet1"/R=(A2,B100)/COLT="1T1N"/NAME="Col1Name;Col2Name;"/D/T UserFileNm

to load the first two columns of a spreadsheet containing labels (col1) and numeric values (col2).
In Igor7 there is a built-in symbolic path named IgorUserFiles so you can write your snippet without using a full path like this:
XLLoadWave/P/S="Sheet1"/R=(A2,B100)/COLT="1T1N"/NAME="Col1Name;Col2Name;"/D/T/P=IgorUserFiles "FileNm.xlsx"
