<P><FONT SIZE=2>The single quote is handy to get a double quote character in the output.<BR>
As to the unsplit. Note that [unsplit ..] is one of the arguments to the catenate. The catenate does not operate on the content.<BR>
And yes the output must have the " " in there because the __FILE__ type items wind up quoted by the preprocessor (at least most pre-processors). That is why I suggested generating the content rather than using those. It would make it much simpler.<BR>
You can get __DATE__ and __TIME__ by [collect date ...]<BR>
And you have the file name within the recipe as %.cpp (or whatever your source recipe uses)<BR>

<BR>
Jerry, thanks for the reply.<BR>
<BR>
It looks like you're using single quotes around the part after the equal<BR>
signs. That's smarter than what I did, since it'll remove all of those<BR>
\\\" from it.<BR>
<BR>
I don't understand the use of unsplit, though. It seems to be producing<BR>
the equivalent to<BR>
<BR>
' " __FILE__ " " __DATE__ " " __TIME__'<BR>
<BR>
after you apply the catenate. What's the reasoning there? Is unsplit a<BR>
good idiom in this case?<BR>
<BR>
Also, Jeff had suggested using the quote function. I went through the<BR>
manuals but there's not much on it. I'll keep looking at that.<BR>
<BR>
Thanks again,<BR>
Mike<BR>

Many times it is easier to use some cook functions to create such<BR>
strings.<BR>
The following pretty much does what you want but for a couple things.<BR>
I did not include the newline characters because they result in a<BR>
compiler<BR>
warning about multiline string constants. Also using __FILE__ etc must<BR>
rely on pre-processor concatination. I believe it might be easier to<BR>
construct that data within the cook recipe and build the whole literal<BR>
string.<BR>
