The SYSIN file in the OP's JCL was the source member for the compile. It has no relation to the program's execution other than the coincidence of the name SYSIN. Very likely, this caused some confusion.

Obviously the OP is working on learning COBOL and JCL, and possibly many other things. Feel free to continue training, but you should consider the audience's level of understanding, not to mention the limitations of an email list for instruction.

Sure. And there is a dataset with SYSIN data on it, which implies no human 
intervention. What do we do now, explode due to the contradiction?

As I said, my guess is a non-Mainframe training example applied to the 
Mainframe.

For a COBOL program on the Mainframe, I see no point in "interacting" in TSO. 
It doesn't happen in the wild. Why learn how to do it? Learning for learning, sure, but 
not as training for COBOL on a Mainframe.

The original program includes the following statements:

            DISPLAY "TO END PROGRAM, ENTER 0.".
            DISPLAY "TO CALCULATE SALES TAX, ENTER THE SALES AMOUNT.".

The above statements are executed prior to "ACCEPT"ing every inputted amount.   
If the intent of this program was to receive input from a file, why would these 
statements be within the source?  Why would they be repeatedly executed?
