ECHO bug

[Roedy]

echo "[!-- macro Moved reunion/reunion.html --]" ] E:\mindprod\reunion\index.html

Angle brackets are shown as square brackets.

Puts the text in the index.html but also the surrounding quotes.

I did not notice this before because I used my own MASM Echo-like utility that stopped working with Windows 7.

If you figure it is too late now to fix this, please warn folks in the documentation.

I've had issues with that before. Somehow the quoting behavior in ECHO more
often surprises me than in other commands. I believe that using back quotes
has always worked for me. This assumes you can change your source.

echo `[!-- macro Moved reunion/reunion.html --]` ]
E:\mindprod\reunion\index.html

Do you mean in your example above you used braces "[]" where the command had
angle brackets "<>"?

AFAIK it has worked that way even in 4DOS. If you use the accent grave (also
known as back-tick, `) to quote the text you will observe what you
apparently desire, i.e. the command below (using your angle bracket to brace
substitution)

echo `[!-- macro Moved reunion/reunion.html --]` ]
E:\mindprod\reunion\index.html

will store

[!-- macro Moved reunion/reunion.html --]

in the target file. Note that any character other than the ` character
itself is written to the target without interpretation.

Another method of writing text containing characters meaningful to the
parser is the use of the TEXT command:

TEXT ] E:\mindprod\reunion\index.html
[!-- macro Moved reunion/reunion.html --]
ENDTEXT

Those characters could also be escaped with ^.

And their special meaning can be turned off with SETDOS /X-6.

This is WAD; definitely *not* a bug. (It's also exactly how CMD.EXE
behaves.)

Did you expect ECHO would remove double quotes? (If so, why?)
