SAY! is like DOS/Windows/Take Command ECHO with easily embedded control characters.
It lets you echo both text and control characters to pipes or files to construct small files on the fly in bat files.

You specify embedded control characters as their decimal number
equivalents e.g. 7=bell 8=Bs 9=tab 10=Nl 12=form feed 13=Cr
SAY! empty 13 10 > dummy.txt
SAY! Y 13 | DEL *.*
SAY! 27 &l5257.1058J 26 > LPT1:
SAY! 7 7 7 The sky is falling

SAY! first line 13 10 second line 13 10 > tinyfile.txt
will put two lines to the file with CrLf line terminators.

Use it to send control strings to a printer, or simulate keystrokes to a
program.

Generates arbitrary strings for pipes or redirection. It fixes a design
flaw in Windows and Take Command ECHO.

say! contents > somefile.txt

will put just the letters contents into the file, not the quotation marks

SAY! is very similar to SAY in the Ziff Communications PC Powertools.
Raymond Hettinger also wrote a very elaborate SAY program based on SAY!
that allows you to use mnemonics like ETX instead of 3.

There are two versions included, both with source:

ASSEMBLER version say!.com that works in DOS/W3.1/W95/W98/Me/NT/W2K/XP/W2K3/Vista/W7-32

and a 32-bit C version say!.exe that works in W95/W98/Me/NT/W2K/XP/W2K3/Vista/W7-32/W7-64

Use the say!.com version except for Windows 7 64-bit. It is smaller faster, and it does the right thing
with:

say! 13 ghosts > file.txt

the com version will put 13 ghosts into the file.
the exe version will but ghosts into the file with a leading Cr character.
