SAS Studio :%LET _EXECENV=SASStudio; 49------NOTE 49-169: The meaning of an identifier after a quote

[HappySASUE]

I use SAS UE or SAS studio consistently.  Until this morning there is no error or issue and run successfully. However suddenly the program stop run and give me "Note", please see example of SAS code and log file below. it runs half code after I restart SAS studio, but stop around half of code. this is very frustrating, I can't have my any work done. 

All my codes are untouched, why it runs a second ago but stop this time?  I uninstall and install the newest version of virtualBox (VirtualBox-5.2.6-120293-Win) and SAS (unvbasicvapp__9411011__ova__en__sp0__1), still doesn't run.  Anybody has the same issue? how to handle it? 

I attached SAS and log file for illustration purpose.

NOTE 49-169: The meaning of an identifier after a quoted string might change in a future SAS release. Inserting white space between a quoted string and the succeeding identifier is recommended.

Sounds like you have unbalanced quotes (or parentheses or %macro/%mend ...) and it is causing SAS to get confused.

Reset the server session and start over. 

If you cannot locate the problem then submit the program in pieces until you locate it.

Note there is no reason to add macro quoting around this string literal. It already has regular quotes!
