After I save a file in a z/OS ISPF it becomes like this
****** ***** Top of Data ***
000100 hello
****** ***** Bottom of Data ***
My Question is, how do I add more lines to this ISPF editor
In other words, how do I make the editor full window again where I can freely type
Use the I(nsert) line command to insert lines after the line where you type the In - n being the number of lines to insert. The default is 1.
All you really need to know is available by pressing the help key - ususally F1.
