Ebcdic() action
The Ebcdic() action returns part or all of the contents of the screen buffer as EBCDIC values. It uses 0-origin coordinates; the upper-left corner of the screen is row 0, column 0.
Each screen buffer position is returned as a 2-digit hexadecimal number, e.g., 81 for the letter a.
Start Field characters are returned as 00.
Each row on the screen becomes a separate line of output, with each buffer position separated by spaces.
Note: The Ebcdic1() action, which uses 1-origin coordinates, is preferred.
