Hello,   I am trying to see the different functionality of SAS. And I just started learning SAS. Using trial SAS (ONLINE--in WINDOWS)  https://azureuse011379.my-trials.sas.com/SASStudio/    I defined a filename as filename cells 'D:\SAS\lwmask0_12US2.txt'; When I tried running the code, I am getting the following error: ERROR: Physical file does not exist, /opt/sas/viya/config/var/tmp/compsrv/default/399cb605-fc7a-47a9-99fb-cca75e5726fa/SAS_workCA7F000000BD_sas-launcher-1d7ea85f- c99c-477c-9174-f48c77cff9b8-nqfhx/D:\SAS\lwmask0_12US2.txt.   I checked : File exists in D:\SAS File can be opened in notepad File is not open anywhere when running SAS I tried changing slash  \  to /  But nothing works.   Why I see a Linux file path?. Any suggestions would be greatly appreciated.   Thanks ... View more
