Fast load Error

Hi 
I am getting error while trying to run a fastload script. The error says " FDL4822 DEFINE statement rejected".
Below is the script:
.logon abcd/passwd;
.set record vartext "";
create table abc
(
eno. interger,
ename varchar(20),
dno integer,
sal decimal(10,2)
)
unique primary index(eno);
.DEFINE
eno (varchar(20)),
ename (varchar(20)),
dno (varchar(20)),
sal (varchar(20));
.BEGIN LOADING abc
.ERRORFILES
emp_err1,emp_err2
.CHECKPOINT 10000
File = file path
show;
insert into abc
(
:eno,
:ename,
:dno,
:sal
);
.END LOADING;
.logoff;
