I came across a code from a previous co-worker that no longer works with us and I've been learning and to continue to maintain and improved on it.
at the very start of his code he created variables
%let UserID = 123456
%syslput UserID = &UserID.;
I don't understand what the point of creating the user ID then doing a %syslput afterwards to what it seems replace the variable? I don't fully understand the %syslput other than its to store variables server side? (I think) I did go through the SAS programming 1 and 2 and part of 3 and i don't recall coming across the %syslput
When i do run the code i get an error saying "ERROR: A link must be established by executing the SIGNON command before you can communicate with UNKNOWN."
Any guidance or help would be appreciate it.
