Array reference creates trailing spaces when called

Samiresh — Wed, 05 Jun 2019 17:31:51 GMT

When ever i call upon the array reference it creates trailing or leading spaces which causes the program to fail. Please observe the below code where in the array reference i insert the size of the dataset and i call it to use in naming convention

i used such naming convention before and it never failed. is it some settings i should turn on or i am missing any syntax

table - trigger file

Name	Date	place
Rock	5	RI
Bye	3	NY
Max	2	ST
Your	1	PC

code

data trigger_file_s1;
set trigger_file;
row_num = _n_;
run;
proc sql noprint;
select max(row_num) into :max_size
from trigger_file_s1;
quit;
data tablename_&max_size.
set trigger_file_s1;
run;

Error log:

MPRINT(DATAINGESTION): data trigger_file_s1;

That's a result of using INTO within SQL. Eliminate the extra blanks by adding:

%let max_size = &max_size;

before trying to use the macro variable

Issue is with the misisng semicolon after tablename_&max_size.

keep the semicolon and it should work.

data trigger_file_s1;
set trigger_file;
row_num = _n_;
run;
proc sql noprint;
select max(row_num) into :max_size
from trigger_file_s1;
quit;
data tablename_&max_size.;
set trigger_file_s1;
run;
