EXITOUT: exit main ENDP END main There are good examples of file IO in Chapter 11 of the text book. In addition you can view the help for the Irvine Library here. Ihttp:l amming.msic.edulasm Your Task! p70 p509tt ch 1stb Write a program that creates a new text file. Prompt the user for a Players name, batting average, and slugging percentage. Write this information to the file one record per line all items comma separated like the following: Glenn Stevenson, Average: .310, Slugging 850 You should have a loop mechanism that vwill allow users to input as many records as the wish. In other words ask if they want to input another record. To make your life easier you are probably going to want to treat all fields as text

1. When run the above program, below window will appear. Fill player details and click on "Input" button, that will open a new file/existing file and write player data.

2. "Input another record" button is used to clear the existing player details in the window.

3. "Exit" button is used to exit from/close the window.

4. Below is the sample player data file.
