I am moving some SAS 9 static reports to parameterized SAS EBI reports
accessed through Web Portal. If the user enters parameters that yield
no results, there is no output (for PROC PRINT, for example): this may
lead the user to believe the system is broken. I made a macro to check
for no observations, but I don't see a good way to display the error
message to the user (apparently through ODS).

I've tried various methods including

#1
ODS text='There are no results: try different parameters'

But SAS doesn't flush the output, so this is never displayed on its
own.

#2
data _null_;
input lines $ 1-80;
file print;
put _infile_;
cards;
There are no results: try different parameters
run;

But cards is not allowed in a macro (which I need to check the count
of observations)

How about this?

data _null_;
file print;
put "There are no results: try different parameters";
run;

The log shows it executes, but ODS doesn't show any output.

NOTE: 1 lines were written to file PRINT.
NOTE: DATA statement used (Total process time):
real time 0.02 seconds
cpu time 0.00 seconds




I also tried this

data _null_;
set sashelp.class;
if _n_ = 1
then
do;
declare odsout obj();
obj.format_text(data: "bla .. bla..");
end;
obj.format_text(data: name);
run;

Which gives the following log but still no output


WARNING: DATA step interface is preproduction in this release.
NOTE: DATA statement used (Total process time):
real time 0.02 seconds
cpu time 0.01 seconds

NOTE: There were 19 observations read from the data set SASHELP.CLASS.

The way you use ods data step interface is not quite right, you need
table_start(), tabel_end() statement.

A more simple way would be using proc print:

data dum;
a="There are no results: try different parameters";
run;

ods ...

proc print data=dum noobs label;
label a='A0'x;
run;

ods ... close;
