SAS数据集“不存在”？

Question

Yesterday I renamed a SAS dataset using my OS. (instead of doing it within a SAS environment). Now, I can see it in my SAS explorer, but when I try to access it SAS tells me that it doesn't exist. I was able to recall the name that I had given the set originally, change it back "manually" and then access it through the interactive SAS environment but, my question:

What the heck is going on here? Is this a flaw in my particular version of SAS or is this just how it is?

Answer 1

Member names in SAS must be valid SAS names. So you couldn't name your dataset 1979data.sas7bdat . You can relax some of the restrictions by setting the option VALIDMEMNAME to EXTEND and using name literals in your SAS code.

But also note that file names on case-sensitive file systems, like Unix, must be all lowercase. So you couldn't use uppercase letters in the name of the file. So SAS would not see a file named OldData.SAS7bdat because if you tried to access a dataset named xxx.OldData it would be looking for a file named olddata.sas7bdat instead.
