Wenn ich in google schlau geworden wäre würde ich hier nicht fragen, trotzdem danke
Unter DOS bis einschliesslich version 7 gibt es dafür wohl keine Hilfe vom OS.
Wenn ich das richtig sehe geht es ab Windos NT mit cmd. exe und dem "set /p"-Befehl:

Für pures DOS würde ich sonst eine kleine Anwendung mit INT 21 AH=0A schreiben, womit eine Eingabezeile mit blinkenden Cursor erscheint und wo man eine vorher festgelegte Anzahl an Zeichen eintippen und mit der Eingabe-Taste übernehmen kann. Danach wird eine neue Textdatei mit den vorher eingetippten Zeichen erstellt und die Anwendung beendet. Danach kann diese Textdatei anderen Anwendungen als Parameter mit übergeben werden. Anschliessend wird diese neue Textdatei wieder gelöscht.
Dafür nötige Software-Interrupts:
INT 21h Funktionen BUFFERED INPUT, CREATE FILE, WRITE TO FILE, CLOSE FILE
RBIL->inter61b.zip->INTERRUP.F
Code: Alles auswählen
--------D-210A-------------------------------
INT 21 - DOS 1+ - BUFFERED INPUT
AH = 0Ah
DS:DX -> buffer (see #01344)
Return: buffer filled with user input
Notes: ^C/^Break are checked, and INT 23 is called if either detected
reads from standard input, which may be redirected under DOS 2+
if the maximum buffer size (see #01344) is set to 00h, this call returns
immediately without reading any input
SeeAlso: AH=0Ch,INT 2F/AX=4810h
Format of DOS input buffer:
Offset Size Description (Table 01344)
00h BYTE maximum characters buffer can hold
01h BYTE (call) number of chars from last input which may be recalled
(ret) number of characters actually read, excluding CR
02h N BYTEs actual characters read, including the final carriage ret
--------D-213C-------------------------------
INT 21 - DOS 2+ - "CREAT" - CREATE OR TRUNCATE FILE
AH = 3Ch
CX = file attributes (see #01401)
DS:DX -> ASCIZ filename
Return: CF clear if successful
AX = file handle
CF set on error
AX = error code (03h,04h,05h) (see #01680 at AH=59h/BX=0000h)
Notes: if a file with the given name exists, it is truncated to zero length
under the FlashTek X-32 DOS extender, the pointer is in DS:EDX
DR DOS checks the system password or explicitly supplied password at
the end of the filename against the reserved field in the directory
entry before allowing access
SeeAlso: AH=16h,AH=3Dh,AH=5Ah,AH=5Bh,AH=93h,INT 2F/AX=1117h
Bitfields for file attributes:
Bit(s) Description (Table 01401)
0 read-only
1 hidden
2 system
3 volume label (ignored)
4 reserved, must be zero (directory)
5 archive bit
7 if set, file is shareable under Novell NetWare
--------D-2140-------------------------------
INT 21 - DOS 2+ - "WRITE" - WRITE TO FILE OR DEVICE
AH = 40h
BX = file handle
CX = number of bytes to write
DS:DX -> data to write
Return: CF clear if successful
AX = number of bytes actually written
CF set on error
AX = error code (05h,06h) (see #01680 at AH=59h/BX=0000h)
Notes: if CX is zero, no data is written, and the file is truncated or
extended to the current position
data is written beginning at the current file position, and the file
position is updated after a successful write
for FAT32 drives, the file must have been opened with AX=6C00h with
the "extended size" flag in order to expand the file beyond 2GB;
otherwise the write will fail with error code 0005h (access denied)
the usual cause for AX < CX on return is a full disk
BUG: a write of zero bytes will appear to succeed when it actually failed
if the write is extending the file and there is not enough disk
space for the expanded file (DOS 5.0-6.0); one should therefore check
whether the file was in fact extended by seeking to 0 bytes from
the end of the file (INT 21/AX=4202h/CX=0000h/DX=0000h)
under the FlashTek X-32 DOS extender, the pointer is in DS:EDX
SeeAlso: AH=28h,AH=3Fh"DOS",AH=93h,INT 2F/AX=1109h
--------D-213E-------------------------------
INT 21 - DOS 2+ - "CLOSE" - CLOSE FILE
AH = 3Eh
BX = file handle
Return: CF clear if successful
AX destroyed
CF set on error
AX = error code (06h) (see #01680 at AH=59h/BX=0000h)
Notes: if the file was written to, any pending disk writes are performed, the
time and date stamps are set to the current time, and the directory
entry is updated
recent versions of DOS preserve AH because some versions of Multiplan
had a bug which depended on AH being preserved
SeeAlso: AH=10h,AH=3Ch,AH=3Dh,INT 2F/AX=1106h,INT 2F/AX=1227h
