I am trying to take an image that's stored in my directory, e.g. '~/' and convert the image into a base64 string using SAS Viya 3.5.  I can convert text strings to base64, but am having issues with actual images.

Is it a different image you need to encode each time?

There will be different images to encode.  I found out from the solution post that I can utilize the x commands in SAS along with macros to complete what is needed.  Thank you!

Thank you.  I was able to utilize the x command and write it to a file to accomplish what I needed.

If you want to reliably automate external commands from SAS, I recommend to not use the X statement, as it gives you no real information about success or nonsuccess (apart from setting &SYSRC).

Instead, use a pipe:

filename oscmd pipe "<your command here> 2>&1";

data _null_;
infile oscmd;
input;
put _infile_;
run;

All output created by the external command(s) will be written to the SAS log. Since the 2>&1 construct reroutes stderr to stdout, all error messages are also caught and preserved.
