SUPPORT / SAMPLES & SAS NOTES
Problem Note 64651: The error "The text expression length . . . exceeds maximum length" appears after using a %SUPERQ function and a text-string value greater than 32K
 |  |  |  |  |
You submit code that contains the %SUPERQ function, and the function contains a value that is greater than 32,000 characters. The following inaccurate messages then appear in the SAS® log:
ERROR: The text expression length (-32767) exceeds maximum length (65534). The text expression has been truncated to 65534 characters.
ERROR: Maximum level of nesting of macro functions exceeded
ERROR: Maximum level of nesting of macro functions exceeded
This code example can generate the errors:
data _null_;
length x $ 32767;
x = repeat('x',32767);
call symput('x',x);
run;
%put Length of mvar: %length(&x);
%let x2=%superq(x);
%let y=1;
%let x=&x&y;
%put Length of mvar: %length(&x);
%let x2=%superq(x);
length x $ 32767;
x = repeat('x',32767);
call symput('x',x);
run;
%put Length of mvar: %length(&x);
%let x2=%superq(x);
%let y=1;
%let x=&x&y;
%put Length of mvar: %length(&x);
%let x2=%superq(x);
