How to check if a PC file exists without using the FileExists function

[Michael_W]

I am looking for a way to verify that a PC file (e.g. test.csv) exists before I attempt to read it into my process through a data step.   The obstacle is that I am not able to use the FILEEXISTS function as the my company has disabled users' ability to use CMD line operations (per corporate policy).  I am hoping that someone else has an alternative method to accomplish the same objective. 

Thank you in advance for your consideration.

The SAS FEXIST function doesn't require OS command line access.

Why would FILEEXISTS() not work because of the NOXCMD option?

It seems to work for me.

1    %put %sysfunc(getoption(xcmd));
NOXCMD
2    %put %sysfunc(fileexist(~/autoexec.sas));
