Charlie; if your friend is lucky enough, she just might be able to
accomplish this task with very little effort through SAS's Cross-Environment
Data Access (CEDA). CEDA is relatively "new" and allows Version 7 and later
SAS data sets CREATED ON OTHER PLATFORMS to be read by Version 7 and later
SAS software. There are a couple of caveats, such as a degradation in
computer performance when processing SAS data sets through CEDA, but, what
the heck? At least she will be able to read the darn thing!
CEDA is included in BASE SAS software, and you do not have to invoke any
special options or procedures to use it. Your friend should simply execute
a CONTENTS Procedure against the SAS data set and see if the CONTENTS
Procedure works. If it does, cool; if not, oh well!
If the CONTENTS Procedure works, she should see something like "VAX" or
"VMS" or whatever in the HOST CREATED field.
One thing that I would heartily recommend is that she have MSGLEVEL=I set in
a SAS OPTIONS statement. Once done, she will get the following type of
message every time she processes a SAS data set through CEDA:
INFO: Data set SASLIB.Charlie.DATA is in a foreign host format.
Cross Environment Data
Access will be used, which may require additional CPU resources and
The message, above, is important because it reminds one that he/she is
processing a SAS data set from a foreign platform and that there _IS_ a
performance penalty. I, personally, do not want to lose sight of which data
sets came from where.
Charlie, best of luck to your friend as she attempts to crunch a VAX SAS
data set on her PC!
I hope that this suggestion proves helpful now, and in the future!
