SAY.COM -- by Serge Couture, PC Magazine, 11-25-86, p. 337
SAY, among other things, may substitute for ECHO. It will print any text
characters from the command line that are enclosed within quotation marks (").
If you want to echo the quotation-mark character itself, use a pair of
quotation marks. If the quotation mark is the first character to be echoed,
triple the quotation marks. If decimal ASCII code values are entered on the
command line without embedding them within quotation marks, SAY will handle
nonprintable characters. Redirection or piping characters (<,>, and |) must be
represented as ASCII values (60, 62, and 124), because DOS will try to redirect
or pipe a command, when it sees the actual symbols on the command line.
EXAMPLES:
STATEMENT: SAY """Compaq?"" he asks." 13 10 "She answers ""PC AT."""
RESULT: "Compaq?" he asks.
She answers "PC AT."
STATEMENT: SAY 27 "&16D" >PRN
RESULT: Sends an Escape sequence to the printer and shows the actual
characters that are being sent
STATEMENT: SAY 27 "[0;68;""CLS"";13;""DIR /P;" ";13p"
RESULT: Redefines F10 to do a clear screen and DIR /P, if you are
using ANSI.SYS.
STATEMENT: SAY 13 "DISK1" 13 "N" 13 | FORMAT B: /S /V
RESULT: Formats and names a floppy disk without any user intervention.
