SAS 9.3 Pipe Access Device Error Msg - Physical File Does Not Exist

[persephone3]

Greetings,
I am using an unnamed pipe access method and filevar option to read multiple files from a directory. The directory letter in my macro variable (P) is not the directory the error message (C hard-drive) references. Why isn't the filevar option pointing to the indicated directory? I can run a directory list using the filename statement, so the pipe is working correctly.
Thanks in advance for your review.

ERROR MESSAGE - " Physical file does not exist, C:\Documents and Settings\....txt.

Did the path work correctly before attempting the macro variable subsitution? I think that the way you construct your macro variable you need a "\" at the end.

%let my_dir = P:\PCP\Data\from_JMG\; If you are trying to get a listing of the text files in directory from_JMG.

Otherwise your are looking for files P:\PCP\Data\from_JMG*.Txt  which would be files starting with from_JMG in Folder Data.

Also this:

fil2read='&my_dir'||f2r;

may not be resolving the way you want. If F2R values are less than 60 characters the contcatenated value of Fil2Read will have possible many spaces between the UNRESOLVED value &My_DIR and the FR2 text. This would result in an invalid variable name if that's what you are attempting.

As a minimum Fil2Read="&my_dir"||Strip(F2r); is probably needed. Macro variable must be between double quotes to resolve.

I'm embarrased to say but it was simply a change from single to double quotes that was needed.  Thanks much for prompt response and resolution!
