I'v got the error message as follows:
ERROR: Invalid header on file INPUT.REFRANGE.DATA.
The code itslef is very simple, a proc contents with data=libname._all_;
within the libname there are 7 datasets, the other six can be seen
in the output file, only this one gave me the error message, I also
tried to use proc print but got the same error message.
I recall sometimes ago, I saw a simliar question in the SAS-L,
but I can't remember the answer, can somebody give me a clue?
I am using SAS for VMS 6.12 on Alpha box.
