I'm am trying to make a batch script on the Atari Portfolio which uses DIP DOS 2.11 (pretty similar to MS-DOS 2.11). I need to put a blank line in my file and it won't work. I have tried echo., echo/, echo(, echo[, echo], echo+, and echo: When I put for example echo/ in there it just outputs a / on that line. Also ECHO , ECHO <tab>, double spaces etc. does not work. It just says ECHO is off. I guess that shows a difference between DIP DOS and MS-DOS 2.11. Any ideas?

  • Yes, sorry I’ll add that. Commented Jul 13, 2021 at 3:10
  • In that case, I guess there is no other way than typing a file with a single CRLF :) But serious, why wasting a whole line of the little screen space of a Portfolio?

  • CLRF? Huh? I made the program in the Terminator 2 ATM hack: m.youtube.com/watch?v=yB82FNPoiPM. It needs the blank lines still though. Commented Jul 13, 2021 at 3:25
  • CRLF is what an empty line in DOS consists of. Also, if you already made it for the movie, why ask again?

In theory, to output a blank line in MS-DOS 2.x, you need to add a single space after ECHO: ECHO .

This doesn’t work in later versions; there, the documented solution is ECHO followed by a space and then the character obtained by holding down Alt and typing 255 on the numeric keypad. This character is a non-breaking space: ECHO  . (This should also work in MS-DOS 2.x.)

The curious can check page 759 of The MS-DOS Encyclopedia.

If that doesn’t work, create a file containing a single line, and TYPE that:

COPY CON BLANK.TXT

Press Enter then CtrlZ, and in your batch file, use

TYPE BLANK.TXT

to produce a blank line.
