IBM0021S

Explanation
 The CONVERSION condition was raised within a GET
LIST or GET DATA statement with the FILE option. The attributes of
the source data could not be determined. 
 Consider the following
example, where the input stream contained 'PIG'C, 'DOG'.  DCL (A,B) CHAR(14);
GET LIST(A,B);

 The condition will be raised when
the first item is encountered. The value for ONSOURCE would be: "'PIG'C",
and value of ONCHAR would be: "C". The ONCODE associated with
this message is 601.

System action
 The ERROR condition is raised.

Programmer response
 Include a suitable ON-unit in the program
to monitor errors in the input data revealed by the CONVERSION condition.
Use the ONSOURCE and ONCHAR built-in functions to identify the error
and the ONSOURCE and ONCHAR pseudovariables to assign a valid value
so the program can continue processing. Also, check the input data
for correctness before rerunning the program.
