Getting _ERROR_=1 _N_=1

[Ajayvit]

Dear,

While executing below dataset I am getting error.

Can some one help to figure out why is the error and how to correct it.

Data testing3;
infile datalines dlm=',';
input pid name$ ad date9. dc date9. ;
format ad dc date9.;
datalines;

When using LIST input with and explicit INFORMAT you need to add the colon format modifier.

Data testing3;
infile datalines dlm=',';
input pid name $ (ad dc)(:date.);
format ad dc date9.;
datalines;
