Any command entered in the ISPF COMMAND LINE disappears after the successful execution of its intended function. If you want to repeat the same command , you got to re-type it or use some PF key to retrieve the last command entered.
But here is a cool method the make the command entered not to disappear and stay on the screen.
Precede commands with “&“.
&C ‘110-PARA’ ‘220-PARA’
After the execution of the command, the below command stays on the screen.
This way you can entering the same command or modifying the command a little and using it multiple times.
