modifier C is even available in SAS9.1.3

See the relevant documentation for that earlier release at http://support.sas.com/onlinedoc/913/getDoc/en/lrdict.hlp/a000212246.htm

Look at the modifiers for the COMPRESS function. I assume you want the W modifier.

clean=compress(raw,,'wk');

Also look at the COLLATE function to specify a range of values by code number.

For example to keep just the printable basic ASCII codes:

clean=compress(raw,collate(32,127),'k')

Of if you have an old version of SAS where compress does not support the modifiers you can use compress twice.

clean=compress(raw,compress(raw,collate(32,127)));

Why?

It is because you can not open this table in SAS/EG ?

It would help to know what your data really look like. The following post shows to methods for seeing the hex representation of your data, one using SAS and one using a nice freeware tool ( http://www.listserv.uga.edu/cgi-bin/wa?A2=ind0905B&L=sas-l&P=R4105&D=1&H=0&O=D&T=1 ) called hexmad.

Sometimes, what seems like unexplained characters, is actually a different kind of file that can easily be addressed if one knows the kind of file it is.

In short, the Forum could probably advise you much better if they could see the hex representation of one or a couple of your data records.
