SAS can allow the strings up to 32,767 characters long but some times SAS will write a Warning message ‘WARNING: The quoted string currently being processed has become more than 262 characters long. You may have unbalanced quotation marks.’, when you try to keep a character string longer than 262 characters to a variable. It is hard to look back at the SAS code to search for unbalanced quotes.
To make it more clearly I am going to show an example.
I want to add a 263 characters long name to a variable (longvar) and to do that I will simply use a data step… and when I do that I will see the WARNING message in Log.
data TEST;
x=”(SEE DOCTOR’S LETTER)3RD ADMINISTRATION OF MTX WAS DELAYED BY 14 DAYS AND WAS REDUCED TO 1G/M2 INSTEAD OF 5G/M2, PROBLEMS, E.COLI SEPSIS WITH HEART INSUFFICIENCY WITH SINUS TACHYCARDY, PARALYTIC ILEUS, TACHYPNEA , PATIENT DIED ON 21.04.98 FROM MULTIORGAN FAILURE.”;
y=length(x);
put x;
run;
LOG FILE:
There is a SAS option (NOQUOTELENMAX)…
