problem with variable length of output dataset in proc mixed

[Aman4SAS]

Hi All,

My Code id below:

%macro model();
%do i = 1 %to 4;
ods trace on;
proc mixed data=kc.LC_15July;
class org_id;
model dose= &&K&i./solution;
ods output solutionf=kc.model_K&i.;
run;
quit;
ods trace off;
%end;
%mend;
%model();

I am having problem to make my all programe automate due to the variable of output dataset ,length of variable "effect" is $20. , which is truncating excat name of variable .

can i increase the length of variable "effect" during creation , so i will get complete name.

Thanks in advance.

Try the NAMELEN= option on the PROC MIXED statement.
