ISPF Creating a File dataset

How do I use ISPF to create a file dataset with a specified record length and a fixed size?

Specific steps :

1. Log in TSO and enter the ISPF main interface, enter command 3.2, and right CTRL to enter.

2. Enter the assignment data set interface, now customize the dataset information, enter the dataset name, the volume serial number, and then enter the A (ALLOCATE) command in the option, return.

3. Enter the data set detailed settings information, here only need to modify the settings record format and record length, where FB is a fixed block (fixed block), record length 80 refers to 80 characters recorded, OK, after the right key to enter.

4. Display the allocation data set successfully.

5. Edit the file to test whether the allocation record length is valid, and option ENTER = 3.4.

6. Enter the edit command and enter the editor

7. Because the editor has a maximum number of columns of 72<80, it is not easy to test, when the input set number of columns is less than 72 o'clock, the line is full, and then the input will not be appended to the back, but instead of a newline.

It is observed that the last 8 columns of the record have an exception, so the last 8 columns are not normally considered for normal use.
