I have initialized a 1-byte string at the start of my applications to the proper directory delimiter based on the operating system. You can scan the physical path of the WORK libname to determine which delimiter is used, then in your code something like:

i=1; work=pathname(work); do while(i<=length(work) and dirDlm=''); if substr(work,i,1) in ('/' '\') then dirDlm=substr(work,i,1); i=i+1; end; rc=filename('tmp',pathname('work')||dirDlm||'out.txt');

(untested right now)

Or I suppose you could write a method that would translate the file path according to the current OS and code them all the same.

In SAS Version 6.12 and 8 for Windows, SAS will auto-translate directory separators.

data _null_; file 'c:/temp/xyz.lst'; put 'abc'; run;

will show in the log

NOTE: The file 'c:/temp/xyz.lst' is: File Name=c:\temp\xyz.lst, RECFM=V,LRECL=256

NOTE: 1 record was written to the file 'c:/temp/xyz.lst'. The minimum record length was 3. The maximum record length was 3. NOTE: DATA statement used: real time 0.01 seconds cpu time 0.01 seconds

So, as long as you keep things to relative paths, you won't have to worry about anything. If you use absolute paths you have to worry about how to indicate the root.
