Chris,
Thanks for all the great examples!
Can you help me understand what the "in" option does? There are several explanations of "out" (like this post), but "in" seems to not be used much.

My situation is that I need to export a SAS dataset to a cvs file that will be sent in an HTTPS POST call to a REST API (specifically, for Qualtrics.com). Can the "in" option do this? If not, can it be done in SAS 9.4 somehow (proc groovy? or some other method)?

Otherwise, I'll have to produce the CSV and then manually upload it - but it would be nice to automate it.

Thanks!
