Text color turned blue without NOTE:

[whymath]

Hello eveybody. I am writing SAS program and I found this wired phenomenon.

I submit code like this:

data _null_;
  set sashelp.class;

  select(name);
    when ('Alice','Jane');
    when ('John');
    other;
  end;
run;

%put this is test text;

The color of %put statement is black:

If I just remove the comma between 'Alice' and 'Jane' and run this program again , the color of %put statement is blue:

Why the text color of %put statement turn blue without 'NOTE:' prefix?

Ps:

1. I have tried other syntax error but they all failed to turn text color of %put statement blue.

2. If I delete "when ('John');", text color of %put statement will always be black.

It behaves the same in my SAS DMS and Studio:

DMS version: 9.04.01M7P08052020
Studio version: 9.04.01M6P11072018

This is an interesting phenomenon.

If I submit "options nonotes", I got black text by your code.
Is it some kind of bug that causes the NOTE flag to be turned on when the SYSERR value is 1012?

Seems to be related to not having an operation after the WHEN.

Note that is, with something after the when, generates a different error message and the macro put text is black.

61   data _null_;
62      set sashelp.class;
63     select(name);
64       when ('Alice' 'Jane') Put "Name is" Name;
                       ------
                       388
                       76
65       when ('John') ;
         ----
         346
ERROR 388-185: Expecting an arithmetic operator.

ERROR 76-322: Syntax error, statement will be ignored.

ERROR 346-185: No executable statement preceding WHEN statement.

66       other;
67     end;
68   run;

NOTE: The SAS System stopped processing this step because of errors.
NOTE: DATA statement used (Total process time):
      real time           0.00 seconds
      cpu time            0.00 seconds


69   %put this is test text;
this is test text

So I would guess that it has something to do with the particular class of error setting a property way in the background
