Not sure what you mean by 'square'. Is it a special character look like a square? Your copy command should not append anything extra. Have you check the file size of the result is the sum of the size of the three source files? -Frank Hi All, I'm new to dos batch files and am only using to append fil...

Davep, Here is my prototype is the command prompt, you should be able to convert it into a script. To print initial spaces, use echo. instead just echo c:\>echo ^<Markers^> & for /f %i in (x.txt) do @(echo. ^Marker & echo. Time="%i" & echo. Value="%i" &...

Hi, Jeb, Thanks, I thought ^ is 'bitwise exclusive or'. Never thought about it is escape char. -Frank Hi Frank, the 'set' command supports '&' "bitwise and", "| bitwise or" but the & is also the delimeter for the next command on one line. like set /a var=1 & echo hell...

jeb, Thanks! I know it is doable! Again, how do I interpret '^|' and '^&'. I do not seem to find anything reference about these operator(most stuff about DOS scripts I can find by 'set /?', 'for /?', 'if /?', 'call /?', ...) And this equation will fail if I put <space> between ^ and | or ^ and &...

Jeb, Thanks for the detailed explaination. Should I interpret *xx as 'a regular expression to match anything up to xx' rather than 'first occurence of xx'? -Frank %var:*xx=yy% only replaces the first occurence of xx with yy in var, and the results begins with the first occurence (removing of the fro...

I can determine whether it is leap year in couple of lines of batch script(witout using &) and most other scripting language support one-liner equation to determine whether it is leap year. But I cannot figure out how to do this in dos batch script since DOS does not support operator like (a == ...

In some case, I want to use other scripting language(like VB script, perl, awk) to perform certain tasks that is hard to implement in DOS batch script. However, I will still need to create a DOS script to wrap around this other script so that I can run the whole thing with single command(I don't wan...

What I want to do is to return the date 30(or any number but usually less than 90) days from today(or any specified date string like 03/07/2008). I am thinking whether to use VBScript DateAdd function but I would like to use complete DOS Batch command(if the code is simple/short enough) if possible....

Any ideas(simpler) to calculate day of the year? What I can come up so far is to: 1. use 'map and lookup' idea by creating a string which maps the month to total number of days in previous month like: set days=01-00;02-31;03-59;04-90 ... 2. add the resulting value from month to the day value 3. adju...

Can someone explain the example on the 'map and lookup' tips under the 'String manipulation'? m REM ---- Example 2: Translate abbreviation into full string ---- SET v=sun set map=mon-Monday;tue-Tuesday;wed-Wednesday;thu-Thursday;fri-Friday;sat-Saturday;sun-Sunday CALL SET v=%%map:*%v%-=%% SET v=%v:;...
